A Correct answer
Explanation

The number 121 is different because it's the only perfect square in the list (11² = 121). The other numbers (137, 153, 177, 183) are not perfect squares.

AI explanation

121 is a perfect square (11×11), while 137, 153, 177, and 183 are not perfect squares. The shared property linking four of the five numbers is that none of them is a square of a whole number, so the one that is a perfect square, 121, stands apart.
