The correct option is (c).
Explanation
The fundamental astronomical distances within the Earth-Sun-Moon system and the speed of light in space. These figures are standard constants used in physical geography and astronomy.
Statement-wise Analysis:
- Statement 1 is Incorrect. The average distance between the Sun and the Earth is approximately 150 million kilometers (specifically 149.6 million km), defined as one Astronomical Unit (AU). The figure of 50 million km is factually incorrect.
- Statement 2 is Correct. Light travels at a speed of approximately 300,000 km per second. Given the distance of 150 million km, sunlight takes about 8 minutes and 20 seconds (roughly 500 seconds) to reach the Earth. Therefore, "about eight minutes" is an accurate approximation.
- Statement 3 is Correct. The average distance between the Earth and the Moon is approximately 3,84,400 km. This distance varies slightly due to the Moon's elliptical orbit (perigee and apogee), but the stated figure is the standard average value.
Key Takeaway:
The Sun is approximately 150 million km away from Earth, while the Moon is approximately 3,84,400 km away. Sunlight reaches Earth in about 8 minutes.
