I think both B and C are correct.
Carcass , could you please confirm?
The passage states this:
"One would be tempted to conclude that the milk carton is thus superior to a medieval painter’s work; we do not submit to this."
The phrase "we do not submit" implies that the author doesn't agree with the notion. Hence I chose C as the answer.
I think both B and C hold statements that the author doesn't agree with. Could you please confirm this? The explanation in the Verbal Test doesn't address this.
