A. San Antonio
Step-by-step explanation:
Maj. Benjamin Foulois chose the location close to San Antonio, Texas, for a new aviation field in 1916, and that is when HiResKelly Air Force Base was first established. The South San Antonio Aviation Camp, one of the earliest structures in the U.S. Air Force, debuted on March 27, 1917, as one of the first Army Air Service sites for World War I. It operated as an aircraft general supply depot as well as a school for pilots, supply officers, engineers, and mechanics throughout the war.
