What was the first jet fighter used by the RAF?

The Gloster Meteor holds the distinction of being the first jet fighter used by the Royal Air Force (RAF). It began its operational service in 1944 and was a significant advance in aviation technology, representing the transition from propeller-driven aircraft to jet engines. The Meteor was developed during World War II and was utilized primarily for intercepting V-1 flying bombs and enemy aircraft.

The other options, although significant in their own right, were not used by the RAF as their first jet fighter. The F-86 Sabre, for example, was an American jet fighter that gained fame during the Korean War but was never part of the RAF's early jet fleet. The MiG-15 was a Soviet design also utilized during the Korean War and did not serve with the RAF. The Lockheed P-80 Shooting Star, another early American jet, was operational primarily with the United States Air Force and also did not feature in the RAF's early jet operations.
