The prime numbers between 50 and 60 are 53 and 59. Therefore, the correct answer is option 'B' which states that there are two prime numbers between 50 and 60.

Explanation:

Prime numbers are numbers that have only two factors: 1 and the number itself. They cannot be divided evenly by any other number. To determine whether a number is prime or not, we need to check if it is divisible by any number other than 1 and itself.

Finding the prime numbers between 50 and 60 involves checking each number individually to see if it meets the criteria for being prime.

1. Start with the first number in the given range, which is 50.
2. Check if 50 is divisible by any number other than 1 and itself. In this case, it is divisible by 2 and 5. Therefore, it is not a prime number.
3. Move to the next number, which is 51.
4. Check if 51 is divisible by any number other than 1 and itself. In this case, it is divisible by 3 and 17. Therefore, it is not a prime number.
5. Continue this process for each number in the given range until we reach the end, which is 60.

In this case, the numbers 53 and 59 are the only two numbers that are not divisible by any other number except 1 and themselves. Therefore, they are prime numbers.

Therefore, the number of prime numbers between 50 and 60 is 2, and the correct answer is option 'B'.
