Sir i think we can't say iff because if limit cn and an both zero then limit may exists some cases

if limit cn is given to be non zero then we can say iff

we can take an= cn ={1/n} then lim an/cn would be 1 but here lim an=0

if we take an=cn={1/n} then we can't say anything about convergence of bn. but according to question we find a condition when the sequence bn is convergent.

when A is non zero then bn converges that's true but we can't comment on converse part that is if bn converges then A can be zero. In the question they are talking about converse part also that's why a is incorrect
