Answer:

Option C is the right answer.

Step-by-step explanation:

Given is a set in roster form as

A={1,2,3....}

This can be represented in set builder form as the set of all natural numbers greater than or equal to 1.

FIrst option is incorrect because x cannot be the set of real numbers.

Second option is also incorrect because here x is not real number

III option is right because x is the set of all natural number which are equal to or greater than 1.

Hence option III is right.
