Quizplus · Accepted Answer

Parallax can be measured by an observer moving relative to a background. This is how astronomers measure the parallax of nearby stars.

Option B is incorrect as parallax can be measured even for stars, but only the ones that are close enough. Option D is incorrect as parallax is larger for closer objects than it is for more distant objects.
