Average distance of the Sun from Earth?

This question probes a fundamental astronomical fact: the average distance between the Earth and the Sun. Due to Earth's elliptical orbit, this distance fluctuates throughout the year, but an average value is commonly used as a standard reference.

• 150 million km (B) is the correct answer. The average distance from the Earth to the Sun is approximately 149.6 million kilometers, often rounded to 150 million kilometers. This distance is also defined as one Astronomical Unit (AU), a standard unit of length used in astronomy.
• The other options, 100 million km (A), 200 million km (C), and 250 million km (D), are significantly different from the scientifically accepted average distance, making them incorrect approximations.
