A. A light paint would be better in the sunlight and in Earth's shadow for preventing overheating
B. A dark paint would overheat the satellite when it passes through Earth's shadow but not in sunlight
C. A light paint would be better for keeping the satellite cool in sunlight
D. A dark paint would be better for keeping the satellite cool in sunlight
