Answer: The top red square near the axis.
Explanation:
Ok, the Earth's axis is the "line" around which the Earth rotates.
This means that after a rotation, the 3 bottom red boxes will be in the dark side of the diagram ( for example, if you have a ball and you grab it with the logo facing you, when you rotate the ball, the logo will be in the other side, and you will not be able to see the logo).
Now, as the area near the axis actually does not move that much, the red square near the axis (the top red square) will be most likely getting 24 hours of light each day.
