A Correct answer
Explanation

This follows a pattern of repeated squaring: 18 squared is 324, 324 squared is 104976, and 104976 squared is 11019960576. The given options (144, 20736, 429981696) are incorrect - 18 is the only one that doesn't fit the doubling chain. However, 18 is the odd one out as it's the only non-doubled number.
