Detailed Solution

Concept: Pluto's orbit is quite elliptical, therefore there is a big difference between its closest and furthest points from the Sun. At its closest position to the Sun, known as perihelion, Pluto is 4.41 billion kilometres away. At its farthest point, known as aphelion, Pluto is 7.33 billion kilometres away. On average, it is 5.87 billion kilometres away from the sun.
Due to Pluto's very eccentric orbit, there is a substantial 39.5 astronomical units, or AU, separate Pluto from the sun. That distance from the sun is nearly 40 times greater than Earth's.
Pluto's eccentric orbit causes it to not always be at the same distance from the sun. Pluto is 29.7 AU from the sun at its closest.
As a result, choice 1 is the right response.
