Solution 1
We can derive that C=8, L=6, U=7, and E=1. Therefore, the answer is 8671 by OwenTang
We can easily see that C=8, which makes only $(A)8761$ and $(B)8762$ possible. Since the only difference between answer choices and is the last digit and that the last digit in the code word "CLUE" is , we can just find that E=1 and that the answer is 8671. by SuperVince1
