How far is the Sun from the Earth in astronomical units?

The correct response emphasizes that the distance from the Earth to the Sun is defined as 1 astronomical unit (AU). An astronomical unit is a standard unit of measurement in astronomy that helps quantify distances within our solar system. Specifically, 1 AU is approximately equal to the average distance between the Earth and the Sun, which is about 93 million miles or 150 million kilometers. This unit allows astronomers to easily communicate and convey information about distances in space, particularly relative to the scale of other celestial bodies within the solar system.

While the other distances mentioned in the options can refer to various aspects of celestial measurement, they do not correctly define the average distance from the Earth to the Sun as universally recognized in scientific terms. Hence, 1 AU is the most accurate and accepted representation for that distance.
