B and D are correct. A doesn't include 0, C is definitely wrong and E doesn't include 1.

A. ttyS[1-5] A will not work because it is missing a 0 in the [1-5]. If it was ttyS[0-5], then the answer would be valid.

For this one, tty?[0-5], question mark represents if the proceeding character is present or not. So I think the answer is correct if ttyS?[0-5] was an option

We're talking about wildcars (globbing) not regular expressions.
