Correct Answer - Option 1 : Year 2012
Here, out of the four alternatives given above the odd one is option 1 i.e. Year 2012 as It is a leap year and rest other options are normal Years.
So, Year 2012 is the odd one here.
Hence, "Year 2012" is the correct answer.
A leap year is a year which comes every four years and in which February has 29 days instead of 28. To check whether the Year is a Leap Year or not we simply divide it by 4. If the remainder comes zero then it is a leap year.
