Correct answer: B. 2 and 3 only

The Messenger spacecraft was specifically designed to orbit and study Mercury, mapping its surface and investigating its geology and magnetic field. The Voyager 1 and 2 probes were instrumental in exploring the outer solar system, venturing beyond the planets to study Jupiter, Saturn, Uranus, and Neptune, and continuing into interstellar space. The Cassini-Huygens mission orbited Saturn and its moons, not Venus, focusing on detailed studies of the ringed planet.
