Solution:

To be sure that he has a matching pair of socks, the man needs to take out at least 3 socks.

Explanation:

The man has 20 black socks and 20 brown socks, which means he has a total of 40 socks in the drawer.

If he takes out 2 socks randomly, there is a chance that he may have one black and one brown sock.

But if he takes out a third sock, he is guaranteed to have a matching pair, either two black socks or two brown socks.

Therefore, the minimum number of socks he must take out to be sure that he has a matching pair is 3.

Hence, the correct answer is option A.
