Answer 1

The prime number are those numbers which are divisble by or by itself. The prime numbers begin from 2, as 1 is divisble by 1 only. So first 5 prime numbers are, 2, 3, 5, 7, and 11.

The number 4 is not a prime number as it is divisible by 1,2 and 4. So answer is,

2, 3, 5, 7, 11

Option b is correct.
