What is the next number? $2,3,5,7,11,?,17$. A)$12$ B)$13$ C)$14$ D)$15$

The right answer is B $13$
Explanation:
Option (B): We have series is $2,3,5,7,11,?,17$.
Observe that the given numbers are part of a series of prime numbers beginning with $2$.
A prime number is a whole number greater than $1$ with only $1$ and itself as factors.
Now, the missing term will be the prime number after $11$, which is $13$.
Hence, the missing number is $13$.
Therefore, option (B) is right.
