Which of the following MUST yield an integer when divided by 7? Choose the correct choice from the following
A) The sum of Seven consecutive positive integers.	B) The square of a prime number.	C) The sum of two odd integers.	D) The product of three consecutive odd numbers.	E) The difference between a multiple of 8 and a multiple of 3.
For option A: Let the numbers be (x-3), (x-2), (x-1), (x), (x+1), (x+2), (x+3).   Now, (x-3)+(x-2)+(x-1) + (x) + (x+1) + (x+2)+(x+3) = 7(x). Hence A is true. No need to check other answers since there can only be one correct answer.   So, The sum of Seven consecutive positive integers.ns(The sum of Seven consecutive positive integers.).
