Correct Option: B. 2 and 3 only

Strategy: Evaluate each mission's target planet. Identify that 'Cassini-Huygens' is linked with Saturn, not Venus, making Statement 1 incorrect. Confirm 'Messenger' is correctly matched with Mercury and 'Voyager 1 and 2' are associated with the outer solar system. Select only the options containing the correct matches for 2 and 3.

Key Info: **Cassini-Huygens** was a flagship collaborative mission by NASA, ESA, and ASI to study Saturn and its system, including its rings and moons. Launched in 1997, it entered Saturn's orbit in 2004 and deployed the Huygens probe to Titan in 2005.

**Messenger** was a NASA mission dedicated to Mercury. Launched in 2004, it orbited the planet from 2011 until 2015, providing the first detailed mapping of Mercury's surface and environment.

**Voyager 1 and 2**, launched by NASA in 1977, were designed for long-term exploration beyond the main planets. Both flew by the outer solar system giants—Jupiter, Saturn, Uranus, and Neptune—and continue transmitting data from interstellar space, having provided foundational information on the outer planets and the heliosphere.
