Which of the following is a prime number ?

A. 115

B. 119

C. 127

D. None of these

Answer: Option C

Solution(By Examveda Team)

We know that 115 is divisible by 5, so it is not prime.
119 is divisible by 7, so it is not prime.
127 < (12)2 and prime numbers less than 12 are 2, 3, 5, 7, 11.
Clearly, 127 is not exactly divisible by any of them.
Hence, 127 is a prime number.
