Answer #1

The paired t-test is used to evaluate the difference between the two treatments.

the difference between the treatments is consistent from one participant to another. For this T statistics would be larger which means SE(d-bar) would be smaller so will be standard deviation (variance) of the difference scores.

So, option c Is correct.
