To find the unit digit of 653^723, we only need to consider the unit digit of the base number, which is 3.

The unit digit of powers of 3 follow a pattern: 3, 9, 7, 1, and then the pattern repeats.

To find where in the pattern 723 falls, we divide it by 4 (the length of the pattern).

723 ÷ 4 = 180 remainder 3.

So, the unit digit of 653^723 is the third digit in the pattern, which is 7.

Therefore, the answer is A] 7.
