A Correct answer
Explanation

A year is a leap year if it is divisible by 4, but century years must be divisible by 400. 2000 is divisible by 400, so it is a leap year. 1900, 1800, and 1700 are not divisible by 400.

AI explanation

A century year is a leap year only if it is completely divisible by 400. Among the given options, only the year 2000 is perfectly divisible by 400, whereas 1700, 1800 and 1900 are not.
