Answer: A) 2, 7, 9
<u>Step-by-step explanation:</u>
In a sudoku puzzle, there are three rules:
- Each vertical line must contain the numbers 1 - 9, with no duplicates
- Each horizontal line must contain the numbers 1 - 9, with no duplicates
- Each 3 x 3 box must contain the numbers 1 - 9, with no duplicates.
Using logic:
2 must go in the 1st box. It cannot go in the 2nd or 3rd shaded square because 2 is already in that 3 x 3 box.
That leaves the 2nd and 3rd shaded square.
9 cannot go in the 2nd shaded square because 9 is already in that vertical line.
Therefore, 9 must go in the 3rd shaded square.
That leaves the 2nd shaded square.
7 must go in the 2nd shaded square because it is the only number remaining (2 and 9 have already been placed in the other squares).
