The correct answer is A. either, or; neither, nor
Explanation:
Correlative conjunctions are a type of conjunctions or words that link two or more words, clauses or sentence and always include two conjunction or parts. This means this type of conjunction differ from coordinate and subjunctive conjunction because they work in pairs to join different elements and one conjunction depends on the other, this includes pairs such as both/and; neither/nor; either/or and not only/ but also. This implies in the case of the sentence "Either John or Lisa was in the lab, because neither Neil nor I went there today" there are two correlative conjunctions and these are "either/or" and "neither/nor" that link different element in this sentence and are pair or correlative conjunctions.
