Answer 1

Correct choice is (c) Match zero or more characters that are not open parenthesis To explain I would say: The [^…] character class is used to match or draw any one character not between the brackets. One should always be careful while using * and ? as repetition characters as they may match zero instances of whatever precedes them, they are allowed to match nothing.
