Answer 4

Heyo! Finally a question about Astronomy (which is my main major xD)

It would actually be C....it is quite hard for me to explain becuase I would have to explain the parallax as well but read this as to why...

The method is based on measuring two angles and the included side of a triangle formed by the star, Earth on one side of its orbit and Earth six months later on the other side of its orbit. So if the position of the star had not changed then the star is distant.
