If a and b are even integers and c is an odd integer, which of the following would be an odd integer? a + b + c ab - bc a x b x c b x c c (a + b)

A. a + b + c: a + b is even. Add c to even to get odd.

B. ab - bc: both products are even, so the difference is even

C. a x b x c: a and b are even, so the product is even

D. b x c: b is even, so the product is even

E. c (a + b) : a + b is even, so the product is even
