The correct answer is option A, that is, astronomical units.

The astronomical unit refers to a unit of length, roughly the distance from Earth to the Sun. However, that distance changes as Earth orbits the Sun, from an aphelion to a perihelion and back again once a year.

The astronomical unit is utilized mainly for calculating the distances within the Solar system or around other stars.
