Dear Candidate,
This question has multiple answers, mainly C & D.
You can use the properties of transpose to solve it.
You will notice that both the first & second option turn out to be symmetric in nature after you apply the properties of transpose to them.
Whereas similarly you solve third & fourth option, they turn out to be skew symmetric in nature.
Hope you understand the same. Expand the options using the property of transpose & you will get the answer.
Hope it helped. Thanks.
