A life insurance policy with a war exclusion clause will generally:

Why A is correct

A war exclusion clause excludes coverage for death that results from military service in a declared or undeclared war or combat. Because the risk of death in combat is catastrophic and not predictable by the insurer, the clause limits the insurer's exposure. Many policies also exclude death while in active military service. When the exclusion applies, the insurer typically returns the premiums paid rather than paying the death benefit, or pays only a limited benefit. Insurers may remove the exclusion by endorsement for an additional premium.

Why the other options are wrong

• War clauses exclude rather than increase benefits; double indemnity is a separate accidental death benefit feature, not a war exclusion provision. This choice does not fit the arrangement described in the question, so it is clearly not the right option to choose.
• Waiving premiums is the function of a waiver-of-premium rider that is triggered by disability, not a war exclusion clause. Accordingly, this option is not correct because it does not match the specific rule or product that is described in the question.
• The war clause does not create paid-up status; it suspends or removes the insurer's liability for deaths that occur in combat. This option therefore does not match the facts presented in the question and is not the correct answer to select.

Memory hook

The war clause means no combat payout, just the premiums back.
