Location C experiences cooler temperatures at that time because the smaller angle means the sunlight is spread out over a larger area. When the sun's rays hit the Earth at a smaller angle, they cover more surface area and are less concentrated, leading to cooler temperatures. In contrast, a larger angle causes sunlight to be more concentrated over a smaller area, leading to warmer temperatures. Therefore, the correct answer is:
Location C, because the smaller angle means the sunlight is spread out over a larger area.
