Despite the lack of a passage in this question, it is still possible to identify the option containing a subject of <em>ridicule.</em>
The correct answer is: Squealer calls the other animals ignorant.
"To ridicule" means to perform an action that undermines the reputation of someone or something in order to make them/it seem foolish. This is accomplished in the sentence as the subject, Squealer, humiliates the object, the other animals, by calling them "ignorant".
