What type of policy can be converted from one that does not accumulate cash value to one that does?

The correct answer is a convertible term policy because this type of life insurance allows the policyholder to convert their term life insurance coverage into a permanent life insurance policy, such as whole life or universal life, which accumulates cash value. Convertible term policies provide flexibility to the insured, enabling them to transition to a more permanent insurance solution without requiring additional medical underwriting.

In the context of the other options, a decreasing term policy specifically is designed to provide a payout that decreases over the term of the policy, without any cash value accumulation, and it is not convertible. A whole life policy, while having a cash value component, does not begin as a term policy and therefore is not relevant to the conversion aspect. A renewable term policy allows for the renewal of coverage at the end of the term period but does not typically allow for conversion to a cash value accumulating policy. Therefore, the key feature of convertible term policies that enables the transition from a non-cash value policy to one that does accumulate cash value makes it the correct answer.
