Regarding the T distribution

a. its precise shape is determined by whether its a repeated measures t test or an independent samples T test

b. none of the answers are correct.

c. the shape is fixed, it does not change at all.

d. As sample size gets larger, the critical value of T gets smaller.

The answer is :

d. As sample size gets larger, the critical value of T gets smaller

If you see the following critical value of student's t distribution, you will note that as the sample size increases (sample size=degree of freedom+1), the critical value of T distribution gets smaller.
