A1, 3, 5, 7, or 9
B0, 2, 4, 6, or 8
COnly the digit 0
DOnly 5 or only 0
Answer & Solution
Correct answer: B. 0, 2, 4, 6, or 8
1. The divisibility test for 2 checks the last digit of a number.
2. A number is divisible by 2 whenever its last digit is 0, 2, 4, 6, or 8.
3. Odd last digits such as 1, 3, 5, 7, or 9 mean the number is not divisible by 2, and only 0 or only 5-or-0 describe different tests.
