The Correct Option is B
Solution and Explanation
Step 1: Identify the Common Property Among the Given Numbers
- 121, 1234321, and 123454321 are all palindromic numbers (they read the same forward and backward).
- 12421 is not a perfect palindrome because it does not have symmetry.
Step 2: Determine the Odd One Out
Since 121, 1234321, and 123454321 share the same palindromic property, the odd one out is 12421.

- No man knows how bad he is till he has tried very hard to be good. A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is. After all, you find out the strength of the German army by fighting against it, not by giving in. You find out the strength of a wind by trying to walk against it, not by lying down. A man who gives in to temptation after five minutes simply does not know what it would have been like an hour later. That is why bad people, in one sense, know very little about badness — they have lived a sheltered life by always giving in.
