What is the primary responsibility of the Army National Guard Bureau?

The primary responsibility of the Army National Guard Bureau is to manage the Army National Guard's resources and policies. This encompasses a wide range of functions that ensure the efficiency and readiness of the National Guard as a whole. The Bureau serves as the channel through which the states' Guard units receive federal support and guidance, facilitating coordination between the states and the federal government.

By managing resources, the Bureau handles budgeting, personnel policies, training, and readiness operations, all of which are critical to maintaining an effective force capable of responding to both state and federal missions. It also develops policies that govern the National Guard's operations, ensuring that units are well-equipped and prepared for both domestic and overseas deployment.

The other choices focus on specific areas that, while important, do not encapsulate the Bureau's overarching role. Fundraising, recruiting, and health care are aspects of National Guard operations but are not the core responsibility of the Bureau itself. The Bureau's main function is strategic oversight and administration, making option B the correct answer.
