\((36^3 + 36)/36\)

= \([36(36^2 + 1)]/36\)

= \(36^2 + 1\)

We know that when the units digit of the base is \(6\) and the exponent is \(2\), then the unit digit of the square of the base will also be \(6\).

hence, the unit digit of \((36^2 + 1)\) will be \(7\) (i.e. \(6 + 1\)).

Looking at the answer choices, we observe that only answer choice C has \(7\) in the units digit.

The correct answer, therefore, is

C
