Final answer:
SGLI coverage ends 120 days after a servicemember separates from active duty, providing a period to transition to VGLI or a private insurance policy without a health examination. The correct option is (d).
Step-by-step explanation:
Servicemember's Group Life Insurance (SGLI) coverage terminates 120 days after you separate from active duty.
After separation, veterans have the option to convert their SGLI coverage to Veterans' Group Life Insurance (VGLI) or to a commercial life insurance policy within that 120-day grace period without having to prove they are in good health.
This timeframe offers a critical transition period for veterans to ensure they continue to have life insurance coverage after their separation from service.
