I think it's the third option. Not entirely sure though.
The correct answer is capitalist.
Marx had neutral to negative feelings about capitalism - he thought that at one point, the system would stagnate, and would undoubtedly be succeeded by socialism. So capitalism as a system, according to him, was unnecessary. He thought that revolution was necessary to get rid of the system, and conflict theorists agreed.
Since there are no options to choose from, my best answers would be:
encourages, discourages
