Answer:
A. Fly-by missions
Explanation:
A Fly-By mission involves the use of a space probe that flies over a star, takes photographs and analyzes it with its instruments. This is a very effective method and is the most common way to capture images from space.
It was fly-by missions that took the two Voyager ships to the border of the solar system in the 1970s and 1980s, and they are also missions that take spacecraft to distant planets and moons these days.
