Answer:
A) Send probes to relay data from the surface of Jupiter.
Step-by-step explanation:
Jupiter, the largest planet in the Solar System, is a gas giant. This means that this immense world - it is large enough to hold more than 1,300 Earths in its interior - has no solid surface, so it would be impossible for astronauts to land on the planet. However, astronomers have been successful in studying the planet by avoiding probes to relay data from Jupiter's surface.
A curiosity is that they do not know for sure whether the center of Jupiter is solid and, as far as they believe, it is about the size of the Earth and is composed of a core - very, very hot - of molten rocks and metals. So, although there is a possibility that its interior is solid, as you can well imagine, it would not be an especially pleasant surface to step on.
