Virginia Code § 38.2-3330 requires group life insurance policies to include a conversion provision,allowing an employee to convert group coverage to an individual policy without evidence of insurability, typically within 31 days after termination of employment or group eligibility. Option B (conversion) directly describes this right, ensuring continued protection. Option A (nonforfeiture) applies to cash value options (e.g., reduced paid-up insurance) in individual policies, not group-to-individual transitions. Option C (assignment) transfers policy ownership, unrelated to conversion. Option D (incontestability) limits the insurer’s ability to deny claims after a period (e.g., 2 years), not a conversion mechanism. The study guide likely highlights conversion as a key group life feature, with scenarios like an employee leaving a job and converting to a whole life policy, making B the precise answer.
