Which of the following is a common exclusion in life insurance policies?

Suicide within the first two years is commonly cited as an exclusion in life insurance policies. This is due to the insurance industry's practice of implementing a contestability period, which typically lasts for the first two years of the policy. During this time, the insurer may deny benefits if the insured dies by suicide, as they seek to prevent moral hazard and ensure that individuals do not take out policies with the intention of committing suicide shortly after. This exclusion is designed to protect the insurer from claims that arise from pre-existing intentions or conditions that were not fully disclosed at the time of policy issuance.

In contrast, death from heart disease or cancer typically does not fall under exclusion as long as these conditions were disclosed during the application process and the policy was issued. Accidental deaths are generally covered by life insurance policies, as they are not linked to the actions or intentions of the insured that would typically raise concerns for insurers, thereby making the exclusion of suicide the most relevant answer in this context.
