Under a regular premium variable whole life plan, which of the following statements is correct?

In a regular premium variable whole life plan, life protection is indeed the main objective, while the investment component serves as a secondary benefit. This type of policy combines life insurance coverage with an investment vehicle, allowing policyholders to build cash value over time based on the performance of chosen investment options. Although investment growth is a significant aspect, it is primarily designed to provide a death benefit to beneficiaries, illustrating that the focus remains on life protection.

The other options do not align with the characteristics of a variable whole life plan. Withdrawals are typically permitted under these policies, allowing policyholders to access the cash value they have built, which contradicts the statement that they are never allowed. Additionally, while single premium contributions are generally accepted in certain variations of whole life policies, the assertion that they are not allowed is incorrect in the context of variable whole life plans. Finally, top-up premiums can often be made by policyholders, but they can also be facilitated or directed by others, depending on the policy's rules, which means asserting that only policyholders can do so may not be accurate.
