C Correct answer
Explanation

NOT LIKE, IN (set), and ^= are all valid SQL comparison operations: NOT LIKE matches pattern exclusion, IN tests membership in a set, and ^= is a valid 'not equal' operator. The == operator is not valid SQL syntax - SQL uses a single equals sign (=) for equality comparison.
