The gravitational force between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them (as described by Newton's law of universal gravitation). Among the options provided, the pair that would exert the strongest gravitational force, hence be the easiest to detect, is:
**A. the Moon and the Earth**
The Moon and the Earth have significant mass, resulting in a substantial gravitational force between them, making it relatively easy to detect this force with measuring equipment. The other options involve much smaller masses and, consequently, much weaker gravitational forces that would be more difficult to measure accurately.
