• B. 0
• C. 5
• D. 4

Answer 1

The correct option is A

1

Any even number is always divisible by 2. So in this case, if we add 1 to 1728, it becomes 1729 which is a odd number, which is not divisible by 2

$\therefore$ the least number that should be added to 1728 so that it is not divisible by two is 1
