The answer is B , but i want to discuss option E. Is having been wrong here? i eliminated this answer because it's an incomplete thought. Treaty having been blah blah and prohibit .... is incorrect. Please help.

Thanks,

Having been is typically only used in introductory clauses. In this case, 'which' is better used because it clearly defines the Treaty as what was signed in 1996.

When you have an action and a specific time mentioned, we should use only simple past tense for that action. Perfect tense is wrong. Eliminate C and E

D and A - ||ism error

Hence B !

I had a doubt over B. i think we need which before prohibits to make the relative clause parallel.
which was signed.. and which X,Y and Z.

Please clarify my doubts.

B looks like prohibits is the verb of Subject Nuclear Test

Blue Skies.....I also had the same doubt!

Found understandable usage rules within one of the old BTG posts itself.

QUOTE
Usage if "having been" is more than just time sequence, though. ilke other -ING modifiers, this one also requires some sort of relationship between the completion of the activity mentioned in the modifier and whatever action is mentioned in the main clause.

for instance:
having finished all his errands, carlos settled into bed for a nice nap.
--> this is logical; carlos can settle in for a nap because he's done with all his errands, so there's a relationship to justify the use of a modifier.

having finished all his errands, carlos called his wife to find out when she was arriving at the airport.
--> not logical, since this phone call has nothing to do with whether carlos has finished his errands.

Quote:
for eg: having been denied a promotion, the worker resigned (resignation after the denial)
this makes sense, but it's somewhat unlikely that you'll use this sort of construction with the passive voice.
instead, you'd just use the passive participle by itself:
denied a promotion, the worker resigned.

with the ACTIVE voice, however, there are fewer ways to get around using this construction, so you'll see it more often in such scenarios. (note my example above, written in the active.)

in any case, "having" is like "being" in the sense that choices containing it are more often incorrect than correct. however, both of these words are certainly correct at times, so it's important to understand these uses.

UNQUOTE

Hope it helps!

" Having been " is the past participle form and used to emphasize that a first action has been completed before the second action begins.

Here is -

Signing CTBT ------- > Prohibit nuclear explosions + Guidelines for proper handling of radioactive material.


thus we can find that signing of CTBT brought into picture prohibition and Guidelines , hence Having been looks good here...

A quick lesson on VERBing modifiers:

An introductory VERBing modifier implies CONTEMPORANEOUS ACTION: an action happening at the same time as the main verb.
SITTING at the kitchen table, John ATE his dessert.
Here, SITTING implies CONTEMPORANEOUS action -- an action happening as John ATE.
Note:
While the VERBing modifier technically is an adjective modifying the subject John, it also plays an adverbial role, providing context for how John ATE his dessert.

An introductory HAVING + VERBed modifier implies PRIOR ACTION: an action completed before the main verb.
HAVING FINISHED his dessert, John LEFT the table.
Here, HAVING FINISHED implies PRIOR ACTION -- an action completed before John LEFT the table.
Note:
While the HAVING + VERBed modifier technically is an adjective modifying the subject John, it also plays an adverbial role, providing context for how John LEFT the table.

Note also the following:
When these sorts of modifiers are preceded by a COMMA, they refer not to the preceding noun but to the PRECEDING SUBJECT.
E: Nuclear testing on the planet is regulated by the Comprehensive Nuclear-Test-Ban-Treaty, having been signed in 1996 by 71 states.
Here, having been signed seems to refer to nuclear testing (the preceding subject), implying that NUCLEAR TESTING was SIGNED in 1996.
Not the intended meaning.
Eliminate E.
