How many total days of service are needed for NSC Pension eligibility?

To be eligible for the Non-Service Connected (NSC) Pension, veterans are required to have a minimum of 90 days of active service. This requirement establishes a baseline that helps determine eligibility for this financial benefit designed to assist veterans with financial need, particularly those who served during wartime. The 90 days of service acknowledges the veteran's commitment and sacrifice during a critical time in the nation's history, enabling them to access necessary support.

In contrast to the other choices, the 1-day option does not meet the necessary threshold for pension eligibility, as it significantly underestimates the time needed. Option C mentions 180 days, which is also incorrect as the requirement is specifically set at 90 days. The final choice, which states that all service counts, misinterprets the specific criterion of the pension program as it requires that the service must be active duty and must meet the established timeframe. Therefore, the correct answer aligns with the established guidelines for NSC Pension eligibility based on the duration of active service.
