What factor is considered in premium computation based on investment?

The correct choice is based on the fact that premium computation related to insurance or investment products often relies heavily on the concept of investment returns. The 'Investment' factor includes considerations of how the funds are managed and the expected returns from those investments. This can involve assessing the performance of different asset classes, the risk associated with those investments, and how effectively the premiums will be allocated to generate future benefits.

In premium computation, the anticipated performance of the insured's policy over time, based on investment strategies, determines how much premium is necessary to meet future obligations. This consideration helps ensure that the product remains viable and profitable over its term, ultimately affecting the cost to the policyholder.

Interest, loading, and mortality are indeed significant factors in insurance, but they pertain to different aspects of premium determination. Interest relates to the returns on the reserves held, loading accounts for administrative expenses, and mortality refers to the risk associated with the insured's life. However, when it comes to the direct impact of investment strategies on the premiums, 'Investment' is the most critical factor.
