The answer is C. As we need to find even integer.

Hi Dipal :)

Happy to clarify!

We're told that n in an odd integer. That means that n is a whole number that is not divisible by 2. On the other hand, n can have 1 or more digits. Some examples of odd integers are

3, 7, 21, 4017 and 31207

n could be any of these integers and be composed of one or more digits.

I hope this helps :)
