Answer:
Light years
Explanation:
The distance between exoplanets and planet earth is measured in light years. It is defined as the distance covered by light in one earth year. It is equal to
9.46 × 10¹⁵ meters. It is equal to 5.88 trillion miles.
The speed of light is 3 × 10⁸ m/s
Length of earth year is 365 days. On converting days into seconds we get 3.15 × 10⁷ seconds
So, on solving one light year equals 9.46 × 10¹⁵ meters
Hence, the correct option is (c) "light years ".
