The correct answer is A. BGT LOOPS.
A conditional branching instruction is an instruction that causes the program to branch to a different part of the code depending on the value of a condition. In this case, the condition is whether the value of the variable X is greater than the value of the variable Y. If X is greater than Y, the program will branch to the label LOOPS. If X is not greater than Y, the program will continue executing the instructions after the BGT instruction.
B. GOTO 50 is not a conditional branching instruction. It is an unconditional branching instruction, which means that the program will always branch to the label 50, regardless of the value of any variables.
C. X = 5 + Y is an assignment statement. It assigns the value of the expression 5 + Y to the variable X.
D. JMP MOTOR is not a conditional branching instruction. It is an unconditional branching instruction, which means that the program will always branch to the label MOTOR, regardless of the value of any variables.
E. None of the above is a conditional branching instruction.
