Jupiter is the correct answer because it is the largest planet in our solar system. It has a diameter of about 143,000 kilometers, which is more than 11 times the diameter of Earth. Jupiter's massive size is due to its composition, mainly consisting of hydrogen and helium. It also has a strong gravitational pull, with more than twice the mass of all the other planets combined.

Bats manage to avoid obstacles while flying through echolocation. Echolocation is a process where bats emit high-frequency sound waves and listen for the echoes that bounce back off objects in their environment. By interpreting the echoes, bats can determine the location, size, and shape of obstacles, allowing them to navigate and avoid collisions while flying. This ability is crucial for bats, especially when flying in the dark or in cluttered environments where vision alone is not sufficient.

Butterflies have six legs. This is a characteristic feature of insects, including butterflies. Insects typically have three pairs of legs, which adds up to six legs in total.
