Identify the person who is the Chairman of the Joint Chiefs of Staff.

• A. General Randy A. George
• B. General Kenneth S. Wilsbach
• C. Chief Master Sergeant David R. Wolfe
• D. General Dan Caine

Answer: (D)

The position of Chairman of the Joint Chiefs of Staff is held by a four‑star general or admiral and serves as the principal military adviser to the President and the Secretary of Defense. This role is about providing military advice and coordinating among the service branches, not direct battlefield command.

Among the options, the best fit is the individual identified as a four‑star general, since the chairman must be a four‑star officer. The other choices include an enlisted senior noncommissioned officer, who cannot hold the chair, and other four‑star generals whose names do not correspond to the chairman in this context. The key idea is that the chairman is the senior uniformed advisor at the four‑star rank level.
