    Correct answer is D.

    Look at the unit digit of a number, and ignore the other digits. We will denote other digits with dots ( ...). Let's say we have a number ... 3.

    ... 3^2 - 3 = ... 9 - 3 = ... 6

    Check for numbers which unit digit is 1,2,4,5,6,7,8, or 9. They don't satisfy any of the answer options.
