Final answer:
The cash payment option does not increase a policy's cash value.
Step-by-step explanation:
The life insurance dividend option that does not increase a policy's cash value is the Cash payment option. When the policyholder chooses the cash payment option, they receive the dividends generated by the insurance company in the form of a cash payment. This option does not increase the policy's cash value because it does not reinvest the dividends into the policy.
