A
That has a low mutation rate
B
In which natural selection is occurring
C

D
For which environmental conditions are changing
Explanation: 

Detailed explanation-1: -Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error (i.e., genetic drift).
