By what methods may dependents receive death benefits?

Dependents may receive death benefits through the methods of mail or direct deposit, making this the correct choice. Mail allows for the delivery of checks or correspondence that provides information about death benefits, ensuring dependents receive the necessary funds. Direct deposit is a more modern and efficient method, allowing for funds to be transferred directly into the dependent's bank account, which enhances convenience and reduces wait time associated with receiving benefits in the mail.

The other options present methods that are either too limited or not commonly used in relation to receiving death benefits. For example, cash advances or reimbursements are typically not standard for death benefits; instead, they focus on payments made directly as a result of the benefit. In-person requests or bank transfers don't encompass the most prevalent or streamlined methods in the context of death benefits. Lastly, the option of immediate cash payment only excludes other viable methods of payment, such as mail or direct deposit, which are actively utilized for distributing such benefits. Thus, the choice of mail or direct deposit accurately reflects the established practices pertaining to the distribution of death benefits.
