Which of the following forms is used for a parent’s Dependency and Indemnity Compensation benefits?

The form used for a parent’s Dependency and Indemnity Compensation (DIC) benefits is indeed the 21P-534. This form is specifically designed for parents seeking DIC benefits, which provide financial support to parents who have lost a child who was a service member. The 21P-534 form allows parents to apply for these benefits and outlines the necessary information and documentation required by the VA.

In this context, it's important to note that the other forms listed serve different purposes related to veterans' benefits. The 21P-601 is used for applying for a claim for a child’s education benefits under the Dependents’ Educational Assistance program. The 21-530 is for burial benefits claims for veterans, which is not related to parental compensation. The 21-534EZ is a streamlined form for surviving spouses and children to apply for DIC, but it does not pertain to parents. Therefore, the 21P-534 is correctly identified as the necessary form for parents seeking Dependency and Indemnity Compensation benefits.
