A. 12
B. 4
C. 3
D. 2

Answer 1

Hint-Make use of the definition of prime numbers for this (Prime number is a number which is divisible by exactly two numbers that is one and itself).

Complete step-by-step answer:
Prime numbers between 1 and 10

So, 2, 3 , 5 , 7 are the only numbers which are divisible by one and itself.
So, we can write that the prime numbers between 1 and 10 are 2,3,5,7

So, the number of prime numbers between 1 and 10 is 4

Hence, Option B is correct.

Note: Whenever solving problems like these make sure not to include 1 in the list as one is not a prime number as one does not have two factors, it has only one factor.
