Question 1 Explanation:
Here, we use the AND as a accumulator with immediate. F leaves the high nibble whatever it is, 0 clears the lower nibble.
→ The XOR’s don’t reliably clear random bits and ANI OF clears the upper nibble, not the lower nibble.
→ The XOR’s don’t reliably clear random bits and ANI OF clears the upper nibble, not the lower nibble.
