At the solution of Q2............ out of 89,90 & 91 ..... there is only 1 Prime ( not 2)

Oh. You're right.
There was a mistake in the condition 2).
It should be fixed in the following way.

Condition 2) : The least number of the integers is a prime number.

Sorry about the confusion.

In Q2. S2. we can take 59,60,61. 59 and 61 are prime. So is 29 and 31 (If we take 29,30,31). Hence B is insufficent
