A) Ranges of characters can be represented by placing a ~ between two characters. This is true.
B) [^Z] is the same as [A~Y]. This is false. [^Z] means any character except Z while [A~Y] means any character from A to Y, including ~.
C) Both "A*" and "A+" will match "AAA", but only "A*" will match an empty string. This is true. A* means zero or more occurrences of A while A+ means one or more occurrences of A. Therefore, A* would also match an empty string. 
Therefore, option D is the correct answer.
