<u>Explanation:</u>
Twelfth Night, or What You Will is a romantic comedy by William Shakespeare, believed to have been written around 1601–1602 as a Twelfth Night's entertainment for the close of the Christmas season.
In the extract from "Twelfth Night" Duke Orsino trusts Olivia is unfeeling and rejects his affection for her. In addition, he is irate and claims that he has been faithful to her; notwithstanding, she has not. Therefore, he needs to slaughter the kid she adores, despite the fact that he is partial to him, basically with the expectation of offending her.
