There is little difference between the values of t_$\alpha$_/2 and z_$\alpha$_/2 when: A)The sample size is small B)The sample size is large C)The sample mean is small D)The sample mean is large E)The sample standard deviation is small

When the sample size is large, the difference between t-distribution and z-distribution becomes negligible, and both can be used interchangeably. Therefore, there is little difference between the values of tF1F1F1S1_F1F1F10_/2 and zF1F1F1S1_F1F1F10_/2 for a large sample size.
