Solution

## The correct option is B 13As the friends who are sitting in a position numbered as by the prime numbers will get Dairy Milk, we have to first know the number of prime numbers from 1 to 15. The prime numbers are 2, 3, 5, 7, 11, 13 Clearly we can see that there are 6 prime numbers, so 6 of her friends will get Dairy Milk
