According to this cartoon which group of people was opposed to women’s suffrage?

A. Men

Explanation:

The cartoon doesn't seem to represent the middle class or the working class specifically, since it has few cues besides the fact that we can see a man. Also, there is a saying "The Ballot Box is Mine Because it's Mine". Men were already allowed to vote, back then, so putting those two together, we can reach the conclusion that men were the ones opposing to women's suffrage.
