B.
4
Detailed Explanation
Correct Answer: 4
The sizeof operator returns the amount of memory occupied by its operand.
Here, x is declared as an integer:
int x = 10;
The question explicitly states that an integer occupies 4 bytes. Therefore, sizeof(x) returns 4.
Notice that sizeof does not return the value stored in x. The value of x is 10, but its size is 4 bytes.
