Explanation:

In the tragedy "Romeo and Juliet" by William Shakespeare, Tybalt is Juliet's cousin. As we know, the romance between Juliet and Romeo happens in the context of a bloody family feud. Juliet is a Capulet, Romeo is a Montague, and their families have hated each other for decades. Tybalt is not the type to wish to end such a feud. Quite the contrary, he makes a point of feeding his hatred for the entire Montague family.

Having that knowledge, we can easily eliminate options B and C. As for option A, Tybalt cannot be angry about the marriage because he is not privy to that information. Juliet and Romeo have married secretly. We are thus left with option D. After killing Mercutio, Romeo's friend, Tybalt returns to the scene due to his hatred for Romeo and his family. Unfortunately for Tybalt, he ends up killed by Romeo.
