Which of the following pieces of art would be considered a form of social protest?

The question is asking which of the following pieces of art would be considered a form of social protest? But there are no choices provided. Let's give some examples though: 1) something that is forbidden, for example a depiction of democracy in a totalitarian state 2) portraying poverty or misery and showing this to the advantaged elite - it would be a way of "complaining" about the elite (for example paining a sweatshop)
