Solution

The correct option is D
All of these

Whole numbers start from 0 and continue thereafter by adding 1 each time. So 0,1,2,3,4,5... are all whole numbers.

-1 is an integer.

-6.5 is a decimal number, the negative sign doesn't change the fact that it's a decimal.

1 is neither a prime number nor a composite number, hence the statement is wrong.
