A Correct answer
Explanation

Standard conditional jump instructions in assembly include JA (Jump if Above), JO (Jump if Overflow), and JMP (unconditional jump). 'JB' is not a standard assembly mnemonic - the correct instruction for 'jump back' would be something like JMP with a negative offset or a loop instruction. The question asks which is NOT a jump instruction, and JB is indeed the invalid one.
