OA is A
can you tell me "both" vs."each" as a split ?
please explain why each choice is correct / incorrect
that's not actually a split; if you were to replace "both" with "each" in the correct answer, you would have another correct answer.
the problems actually lie elsewhere.
(c) and (d) are incorrect because of the word "and"; the sentence is not presenting two separate, independent facts, so "and" is inappropriate as a conjunction.
(b) and (c) are incorrect because of the tense used; "has dated" implies that this is not the case anymore. (this particular construction really only makes sense in the present tense -- or as an -ing modifier attached to a present-tense clause, since -ing modifiers adopt the tense of the clause to which they are attached.)
(e) has subject-verb disagreement ("each one of which" must be singular).
(d) uses complete sentence + comma + "and", a conjunction that should be followed by another independent clause. since "dating" isn't a verb, that second half is a fragment.
