The correct answer is: A. The square will not be a perfect square.
When you draw a square by holding down the Shift key while dragging the mouse, the square will be perfectly aligned to the cardinal directions (north, south, east, and west). However, if you release the mouse button before releasing the Shift key, the square will be drawn in the direction that the mouse was moving when you released the button. This means that the square will not be perfectly aligned to the cardinal directions and will not be a perfect square.
Option B is incorrect because the square will always be centered on the point where you started dragging the mouse, regardless of when you release the mouse button. Option C is incorrect because the square will always be the same size, regardless of when you release the mouse button. Option D is incorrect because the square will always be a square, regardless of when you release the mouse button.
