Detailed Answer in Step-by-Step Solution:
The grace period in a life insurance policy (typically 30 or 31 days) allows the policy to remain in force even if the premium is unpaid, provided the insured dies during this period.
If death occurs during the grace period, the insurer must pay the full death benefit (face amount), minus any unpaid premium, but only if explicitly stated. In this question, no indebtedness or dividends complicate the scenario, and standard practice assumes full payment unless otherwise specified.
Option B (cash value) applies to surrender, not death claims.
Option C (face amount less premium due) is a possibility in some policies, but absent specific policy language here, the default is full payment.
Option D (nonforfeiture provisions) applies if the policy lapses, not during the grace period.
Thus, the insurer pays the face amount (A).
The Virginia study guide states that the grace period provision protects the policyholder by keeping coverage active for a short period after a missed premium, and upon death during this time, the full face amount is payable unless loans or specific deductions apply.
