Which of the following cannot yield an odd integer when divided by 5?

B. an integer less than 5
C. the product of an odd integer and an even integer
D. the sum of three consecutive integers
E. an even integer minus an odd integer
What is wrong with B??
Let’s test each answer choice:
A) an odd integer squared
Since 5^2 = 25 and 25/5 = 5, an odd integer squared can yield an odd integer when divided by 5.
B) an integer less than 5
Since -5/5 = -1, an integer less than 5 can yield an odd integer when divided by 5.
C) the product of an odd integer and an even integer
The product of an odd and even integer will always produce an even integer.
Any even integer (such as 10, 20, 30, etc.) that is divisible by 5 will always yield an even number.
Answer: C
