Lets go step by step by step, eliminating the given options:
Min string accepted by P is 00 , therefore 3, and 4 cant be the RE for it as they say 01 must be included.
Min string accepted by Q is 00 , therefore again 3, 4 cant be RE for Q for the same reason mentioned above.
So by now, we left only 2 options, answer has to be A or C.
2nd min accepted by P is 001, but RE in 2 says string start and end with 0. Therefore RE for P is 1 making 2 as RE for Q.
Therefore answer is Option C.
