Hi,
*7 = 1.2.3.4.5.6.7
So, it is divisible by all numbers from 2 to 7
So, when we add any number from 3 to 7, the number will still be divisible by that number
*7+3 = 3(1.2.4.5.6.7 + 1)
*7+4 = 4(1.2.3.5.6.7 + 1)
.
.
*7+7 = 7(1.2.3.4.5.6 + 1)
So, there are no primes in the given set of numbers

Hence, A
Cheers!

Between *7 + 3 and *7 + 7 = 7! + 3 and 7! + 7 = 5043 and 5047 .As there are no prime numbers between 5043 and 5047 the answer is none.
Hence, A.
