Three students are debating:Student A: The pressure at level C must now be greater than the atmospheric pressure because liquid there is being pushed up against the stopper. Student B: I think the pressure at level B must be the same as at level A, because they are at the same level. Both are at atmospheric pressure. So the pressure at level C must be lower than atmospheric, because pressure decreases as you ascend. Student C: But the liquid is denser than air, so the pressure at C cannot be less than atmospheric pressure. With which student(s) should you agree
