If the least common subtraction of two prime numbers x and y is 10, where x < y , then the value of 2x + y is	Choose the correct choice from the following
A) 7
B) 9
C) 11
D) 21
E) 31
(x-y) = 10 and both x an y are prime.   The only values of x and y can be 7 and 17 (x = 7 and y = 17)   2x + y = 2*7 + 17=
