Try out each statement with 3, 2 and multiples of 3 and 2 (3:2 =
4:6 = 8:12). If you add 3 + 2, you get 5 which is an odd integer.
If you add 4 + 6, you get 10 which is an even integer (A and B are both
wrong). 3 * 2 = 6 which is divisible by 6 and is even (C and D are
wrong). The product of the 2 numbers can never be odd (E) because
if the numbers have to be integers, then all numbers involved will always
be even (because you are always multiplying by 2 to get the next ratio
of numbers), and the product of 2 evens always is even.
