Final answer:
The accumulation period of an annuity does not occur in a deferred annuity. The correct answer is C.
Step-by-step explanation:
It does not occur in a deferred annuity.
An accumulation period is a period during which the annuity payments accumulate interest. It is the period over which the annuitant makes payments into an annuity, not payments made by the contract holder. A deferred annuity, on the other hand, has a period during which the contract holder makes payments, but no accumulation period since the annuity payments do not accumulate interest during that time.
