Some of your answers are wrong. 10. should be A; 14. should be A,B,C; 15. should be None - the correct expression is ^([^0-9]+)*$; and 31. should be B, although it only applies to vim (in Perl it also matches '_' which is not in the [:alnum:] class).

Beg your pardon, 31. should be A but the clarification still stands.
