Answer 2

Answer:

A correct statement is :

a) The additive identity under natural number is 0.

Step-by-step explanation:

• An additive identity is a number, which can be added to any number and gives the sum as the number itself. So, additive identity is “0” as adding 0 to any number, gives the sum as the number itself.

        Example:

          3 + 0 = 3

          0 + 7 = 7

• For any set of numbers, that is, all integers, rational numbers, and Natural numbers, the additive identity is 0 because when you add 0 to any number, it doesn’t change the number and keeps its identity.

• The additive identity for natural numbers a  is a number b which when added with a, leaves it unchanged. b is called  the additive identity of any natural number a if a + b = a. Now, when we add 0 with any natural/whole number a we get a + 0 = a = 0 + a

• So, 0 is the additive identity for any natural numbers.
