D Correct answer
Explanation

The SR-71 Blackbird is the fastest jet aircraft ever, with a top speed exceeding Mach 3.3 (about 2,200+ mph). While the X-15 was faster (Mach 6.7), it was rocket-powered, not a jet-powered aircraft. The SR-71 used jet engines (turbo-ramjets) and holds the record for air-breathing jet aircraft. Options like X-43A and MC-72 are either experimental or incorrect.
