A Guaranteed Insurability rider allows a policyowner to purchase additional life insurance at specified future dates. What is the key advantage this rider provides?

Why this is the answer

The Guaranteed Insurability (GI) rider—also called the Guaranteed Purchase Option—gives the policyowner the contractual right to purchase additional insurance at predetermined option dates (commonly age milestones or life events such as marriage or birth of a child) without submitting to a medical exam or providing any evidence of insurability. The insured pays premiums based on attained age at the option date, but cannot be turned down for health reasons. Option A describes a Cost of Living rider, not GI. Option B describes Waiver of Premium. Option D describes a conversion privilege, not GI. The TX outline §II.A lists Guaranteed Insurability as a distinct testable rider.
