The number of prime number 50 and 60 [#permalink]
Quantity A: The number of primes between 50 and 60

Prime numbers between 50 and 60 are 53, 59 => 2

Quantity B: The number of primes between 20 and 28

Prime numbers between 20 and 28 are 23, 29 => 2

Clearly, Quantity A(2) = Quantity B(2)

So, Answer will be C.
Hope it helps!
