B is correct. A Straight Life Annuity , also called a life-only annuity, provides periodic income for as long as the annuitant remains alive. Its principal function is therefore to transfer longevity risk to the insurer: regardless of how long the annuitant survives, contractual payments continue for life.

The current Hawaiʻi Life-General Knowledge outline specifically tests annuities, including immediate and deferred annuities, accumulation and annuity periods, and payout options . Hawaiʻi's Insurance Division also identifies qualified tax-deferred annuities among financial arrangements commonly considered for retirement income planning.

Option A is the opposite of the primary characteristic of straight life. Because payments normally cease when the annuitant dies, regardless of how soon death occurs after annuitization, a straight-life payout is generally designed to maximize lifetime income rather than beneficiary protection. Option C is incorrect because tax deferral is not equivalent to permanently tax-free appreciation; taxation depends on the source of funds and applicable tax rules. Option D is also incorrect. A standard fixed straight-life annuity does not inherently provide inflation protection; purchasing power may decline if payments remain fixed while prices increase.

Thus, the defining advantage is lifetime income that the annuitant cannot outlive .
