Generally, COMMA + VERBed serves to refer to the nearest preceding noun.
E: electric current, first made in 1845
Here, made seems to modify current -- the nearest preceding noun -- implying that electric CURRENT was first MADE in 1845.
Not the intended meaning.

NO COMMA + VERBed does NOT have to refer to the nearest preceding noun.
OA: an observation about electric current first made in 1845
Here, made serves to modify an observation, implying that AN OBSERVATION was first MADE in 1845.
This is the intended meaning.
In the OA, the referent for made is NOT the nearest preceding noun.

@ GMATGuruNY - couple of quick clarifications required on VERBed modifier in this SC and as a whole...

1. If we say that in E, COMMA + VERBed ,first made modifies the COMPLETE preceding NOUN Phrase an observation about electric current, then will it be wrong as far as application of VERBed modifier is concerned on GMAT ? ( However, E is still an INCORRECT option for other reasons)

2. NO COMMA + VERBed : So, it may (or may not) refer to nearest preceding NOUN (or NOUN Phrase) on GMAT.
BUT COMMA + VERBed ALWAYS serves to refer to the nearest preceding NOUN (or NOUN Phrase) on GMAT. Did I get you right ?

COMMA + VERBed must serve to modify the nearest preceding NOUN.
In E, COMMA + first made CANNOT serve to modify observation, since observation is NOT the nearest preceding noun.
Rather, it must serve to modify current, the nearest preceding noun.
As a result, E conveys that the CURRENT was FIRST MADE in 1845 -- a distortion of the intended meaning.

COMMA + VERBed must serve to modify the nearest preceding NOUN.
NO COMMA + VERBed may modify either the nearest preceding noun OR the nearest preceding NOUN PHRASE.
In the OA, first made modifies an observation about electric current -- the nearest preceding noun PHRASE -- correctly conveying that AN OBSERVATION ABOUT ELECTRIC CURRENT was FIRST MADE in 1845.

Great explanations. But,

COMMA + VERBed must serve to modify the nearest preceding NOUN.
In E, COMMA + first made CANNOT serve to modify observation, since observation is NOT the nearest preceding noun.
Rather, it must serve to modify current, the nearest preceding noun.

In this case, isn't there an exception to the rule that the preposition phrase can be IGNORED and thus first made can SKIP current to modify observation?

As stated in my post above, a COMMA + VERBed modifier must serve to modify the nearest preceding noun.
To my knowledge, no official SC has disregarded this rule.

one of Kirchoff's laws THAT was an observation about electric current, first made in 1845, and THAT is now included in virtually every textbook of elementary physics.

Eliminate E.
Dear GMATGuru

I agree with about the parallelism of connecting extended 'that' clause. But I wonder if this rule was violated in any official question that you came across. If yes, Can you cite any official question that second 'that' was omitted?

Thanks

Offhand, I cannot cite an official SC that violates the rule discussed above.

look at choice a.

"and" is a hard word on gmat. "and" show that 2 or more than 2 items are parallel grammatically. but we need to prove that the items are parallel logically. this require us to understand meaning clearly . this job is not easy.
"and it is" is popular phrase on gmat sc. we "and it is" shows that there is a parallel pattern and we need to prove that there is a logically parallelism to choose the sentence.
so, "and it is..." need to be parallel logically with a preceding item. "which" can not parallel with "and it is" because "and which" is parallel with "which".
so, "and it is..." must be parallel with an further item. there is no item, which can be parallel with "and it is " logically.
