Solution

The correct option is C 1231
A palindrome is a number, word, or phrase which reads the same forwards and backwards.

Reverse of 121 = 121
Reverse of 1331 = 1331
Reverse of 12321 = 12321
Reverse of 1231 = 1321

Thus, 1231 doesn't read the same when it is reversed, hence it is not a palindrome.
