Which of the fallowing is not a leap year?Question 1Answera.1400b.1564c.2800d.1372

The answer is a. 1400.

Here's why:

A leap year is a year, occurring once every four years, which has 366 days including 29 February as an intercalary day.

The rule is that a year is a leap year if it is evenly divisible by 4, except for end-of-century years, which must be divisible by 400. This means that the year 2000 was a leap year, although 1900 was not.

So, let's apply this rule to the options:

a. 1400 - This is not a leap year because, although it is divisible by 4, it is a century year and not divisible by 400.

b. 1564 - This is a leap year because it is divisible by 4.

c. 2800 - This is a leap year because it is divisible by 4 and, although it is a century year, it is also divisible by 400.

d. 1372 - This is a leap year because it is divisible by 4.
