I've covered this topic in my studies, so I'm feeling confident. I think the answer is B - Regular Expressions are not a supported expression type in a Resource Block.
Definitional Expressions sound like they could be a valid option, but I'm not totally sure. I'll mark that one and come back to it if I can't decide on the others.
