Understanding the Regex Pattern: \[^abc] - Meaning and Usage

The regex pattern [^abc] represents a character class that excludes the characters 'a', 'b', and 'c'. This means it will match any character except for 'a', 'b', or 'c'.

Here's a breakdown:

• [ and ]: These define a character class.
• ^: Inside a character class, this symbol indicates negation, meaning it matches anything not in the class.
• a, b, c: These are the characters to be excluded.

Therefore, the correct answer is C. Matches ^ or a or b or c. This is because the pattern explicitly excludes 'a', 'b', and 'c', so it matches anything else, including the caret symbol ('^').
