The correct answer is D. When the insured survives policy term.
A maturity claim is payable when the insured survives the policy term. This means that the insured must live for the entire length of the policy in order to receive the benefits. If the insured dies before the policy expires, the benefits will not be paid.
Option A is incorrect because it states that the maturity claim is payable when the insured survives the first 5 years. This is not always the case. The maturity claim may be payable after a different number of years, depending on the terms of the policy.
Option B is incorrect because it states that the maturity claim is payable when the insured dies during policy term. This is also not always the case. The maturity claim may be payable even if the insured dies during the policy term, depending on the terms of the policy.
Option C is incorrect because it states that the maturity claim is payable when the insured is diagnosed with a critical illness. This is not usually the case. The maturity claim is usually payable only if the insured survives the policy term.
