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.
Question : What is $\frac{\left (x^{2}-y^{2} \right)^{3}+\left (y^{2}-z^{2} \right )^{3}+\left (z^{2}-x^{2} \right )^{3}}{\left (x-y \right)^{3}+\left (y-z \right )^{3}+\left (z-x \right)^{3}}?$
