C Correct answer
Explanation

Pluto has an extremely elongated orbit that takes it much farther from the Sun than the planets. At its average distance, it requires about 248 Earth years to complete one revolution around the Sun. This long orbital period is why Pluto was only discovered in 1930 despite being relatively bright compared to other distant objects.
