Coorelative conjunctions are parts of speech that occur in compounds and have analogous meanings establishing a balance between words, phrases or clauses. Thus, <em>both...yet</em> is not a coorelative conjuntion.
Correlative conjunctions are conjunctions that are used to connect equal or balanced clauses. These include neither/nor, either/or, both/and, not..only, but...also and whether/or. From the given conjunctions above, the choice that is not a correlative conjunction is option c. both..yet. The pair of both should not be "yet" but "and".
