A.
4 10
Detailed Explanation
Correct Answer: 4 10
This question tests an important property of sizeof.
The expression inside sizeof is x++. Although x++ would normally increase x by 1, the expression is not evaluated in this use of sizeof.
Therefore, x remains 10.
Since x is an integer and the question assumes an integer size of 4 bytes, sizeof(x++) returns 4.
Thus the output is 4 10.
