both dating -is ok (modifier)

both of which have dated- not right tense

and each has dated -no need in "and" , and not right tense

and each one dating -no need in "and"

each one of which date- it should be dateS, since each one is singular

hope it helps

would go with A for both ( which is used for TWO, mentioned in the passage )
would select D if the question had more than TWO communities.

Please correct me if am wrong!

IMO A
C,D are wrong - "and" joins 2 Independent Clauses but we need a Dependent Clause
B,E are wrong because each introduce independent clause without any conjunction

This SC is about an ONGOING TRUTH: that the Acoma and Hopi ARE probably the oldest surviving Pueblo communities, both DATING back at least a thousand years. In B and C, the present perfect (has/have dated) cannot be used to express an ONGOING TRUTH. Eliminate B and C.

In E, one (singular) does not agree with date (plural). Eliminate E.

In D, each one dating back (noun + modifier) is an ABSOLUTE PHRASE. An absolute phrase should not be connected to the preceding clause with a conjunction such as and. Eliminate D.

The correct answer is A.

An absolute phrase:

-- consists of a noun and a modifier and perhaps a few other words
-- is connected to an independent clause WITHOUT a conjunction
-- modifies and provides context for the entire independent clause

For another example of an absolute phrase, check here:

Mitch,
Can we eliminate B and E because each joins 2 independent clause with a comma(,)

No. The second clause is not independent.

Which is a relative pronoun: a pronoun that serves to RELATE one part of the sentence to another. Thus, the clauses that follow the commas in B and E are relative clauses. To be specific, they are NON-RESTRICTIVE relative clauses. Typically, a comma is used to connect a non-restrictive relative clause to the preceding clause.

Mitch,

Can you comment on the use of 'both'?

I always tend to suspect an option that includes 'both' and doesn't follow the idiom structure 'both X and Y', and as a result I somehow find an excuse to eliminate that option.

Thanks
