C Correct answer
Explanation

In this date validity puzzle, '31st June 1999' is the odd one out because June never has 31 days - it only has 30 days. The other three dates are all valid calendar dates. February 29th, 2000 was valid because 2000 was a leap year (divisible by 400).

AI explanation

To determine which word does not belong to the group, we need to identify the word that is different from the others based on a specific criterion.

Looking at the options:

A. 29th February 2000 B. 29th April 1998 C. 31st June 1999 D. 31st August 1997

The criterion that stands out is the month. All options have a day and year, but option C has a month that does not exist.

Therefore, the word that does not belong to this group is C. 31st June 1999.
