e. None of the above

Answer 1

Voyager 2 visited all the Jovian planets in the 1970s and 1980s(option c).

Step-by-step explanation:

The correct answer is option c:Voyager 2.

Voyager 2, launched by NASA in 1977, visited all the Jovian planets in the 1970s and 1980s. It reached Jupiter in 1979, Saturn in 1981, Uranus in 1986, and Neptune in 1989. Voyager 2's trajectory was made possible by the approximate alignment of the four giant planets on the same side of the Sun, allowing the spacecraft to use gravity-assisted flybys to adjust its course for each subsequent encounter. This trajectory has been nicknamed a "Grand Tour" by astronomers.
