Relevant is the root word
It would be B because "You seems happy about the cold weather" does not make any sense but "You seem happy about the cold weather' does make sense.

Khalil’s shooting and the ongoing investigation of Officer Cruise put the theme of injustice at the forefront of the novel. The fact that Khalil was unarmed and did not threaten the officer makes his murder unjust. The police are unjust at other points, too, such as when they force Maverick to the ground and pat him down. Race is tied into this theme of injustice as well, since pervasive racism prevents African-Americans from obtaining justice. Starr and Maverick in particular are focused on bringing justice not only for Khalil but also for African-Americans and other oppressed groups, such as the poor. The activist group that Starr joins is called Just Us for Justice because it fights against police maltreatment on the basis of race. At the end of the novel, Starr accepts that injustice might continue but reinforces her determination to fight against it.
I would say C. because you always include facts when providing good evidence.
