The correct options are
B 3014
D 1994
A century, when completely divisible by 400, is a leap year.
When 2000 is divided by 400, there is no remainder and hence, 2000 is a leap year.
A year that is not a century is a leap year if divisible by 4.
3014÷4 leaves 2 as the remainder.
4016÷4 leaves no remainder.
1994÷4 leaves 2 as the remainder.
Therefore, 4016 is a leap year and 3014 and 1994 are not leap years.
