If you add all the missing literal in the expression then this expression will give the 9 minterms or you can say
Sum(m0,m1,m4,m5,m10, m12,m13,m14, m8)
Now option C and option D have eliminated becoz it has 10 and 11 minterms respectively
Now it's a game between option A and option B . Now look at 0101 or m5 in option A which is minterm of given expression but it is not present in option B .
Warning : X (don't care ) can be treated as 0 or 1 as per our requirement .
So final answer is A.
Hope u like it 😊
