C Correct answer
Explanation

A scramjet carries fuel (usually hydrogen) but scoops oxygen from the atmosphere instead of carrying it onboard, making it more efficient than rockets which must carry both. Option C states scramjets carry no fuel at all, which is false - they eliminate carrying oxygen, not fuel. Since the question asks which statement is NOT true, C is the correct choice.
