□ 8 seconds
rewatch

Explanation:

The speed of light is about 299,792 kilometers per second, and the average distance from the Sun to Earth (the astronomical unit) is approximately 149.6 million kilometers. Using the formula \( t=\frac{d}{v} \) (time = distance / speed), we calculate the time it takes for light to travel from the Sun to Earth. After calculation, this time is approximately 8 minutes. The other options (8 days, 8 hours, 8 seconds) are inconsistent with the physical knowledge of the speed of light and the distance between the Sun and Earth.

Answer:

A. 8 minutes
