Answer:
(A) Taking pictures of other planets during the flyby is the correct and their moons is the correct answer.
Step-by-step explanation:
A spacecraft that fly past a planet or other body for getting information about it is called a flyby. In flyby, the spacecraft passes close without getting caught in the orbit of gravity. It uses instruments for observing the target and the down linking the data to earth, if down linking is not possible then the data is stored on board. The flybys get very limited opportunities to gather information because once it has flown by there is no other chance to observe. The flyby missions are planned and practiced in advance. Different sequences of commands are also used by the flight team for guiding the flyby in various stages during the flyby.
