Solution

The correct option is D
All of these

Natural numbers start from 1 and continue thereafter by adding 1 each time. So 1,2,3,4,5... are all natural numbers. All the natural numbers and "0" together are referred to as Whole numbers. Natural numbers, their negatives and 0 constitute the set of Integers. Hence all the statements are wrong.
