Question

Bailey makes a conjecture that the product of two odd integers is always an odd integer. Which choice is the best proof of her conjecture

Answer 1

D.

Step-by-step explanation:

Let (2a+1) be an odd number, and let (2b+1) be another odd number. The product 2(2ab+a+b)+1 is a multiple of 2 plus 1, which is an odd number.
