Answer: Option A
Answer: (a)Meaning: Evinced - Indicate an interest or feeling, Perpetuated - make something continue indefinitely, Cajole - to influence someone by flattering “But” used for conjunction here, it directly shows that the clauses of the sentence show contrast (positive-negative or negative-positive). With “Backing out” in the second clause which is negative, we find that the verb in first clause must be positive. Evinced which means opposite to “backed out” fits here.
