A: 2

B: 4

C: 1

D: None of these

Best Answer


A composite number is a natural number, i.e. counting numbers that have more than two factors.

That means a composite number is a number that is divisible by more than two numbers.

In other words, a natural number which is not a prime is a composite number other than 1.

For example: - let us consider the natural number 10. 10 is divisible by 1, 2, 5, and 10 itself which means it has more than two factors. 

So, 10 is a composite number. 

Some other composite numbers are - 4, 6, 8, 9, 10, 12,….. etc.

4 is the first and smallest composite number.

Final answer:-

Hence, option (b) is the correct answer i.e. 4
