C)Stays the same
D)Randomly fluctuates

As the Type I error decreases, the threshold for rejecting the null hypothesis becomes higher, making it harder to reject it even when it is false. This also means that the probability of accepting the null hypothesis (Type II error) increases. Thus, as Type I error decreases, Type II error increases.
