To determine the number of squares in the given figure, we follow these steps:

1. First, count the smallest squares. In the figure, there are 9 small squares since it's a 3x3 grid.
2. Next, count the squares of size 2x2. Each 2x2 square requires a 2x2 block from the 3x3 grid. There are 4 possible 2x2 squares.
3. Lastly, count the largest square, which is 3x3. There is only 1 such square possible in the whole grid.

Thus, the total number of squares is calculated as follows:

• Number of 1x1 squares = 9
• Number of 2x2 squares = 4
• Number of 3x3 squares = 1

Total number of squares = \(9 + 4 + 1 = 14\).

Therefore, the correct answer is 14.
