B Correct answer
Explanation

The Sun is approximately 150 million kilometers from Earth, and light travels at about 300,000 km/s. This distance takes light roughly 8 minutes to cross, so if the Sun disappeared instantly, we would continue seeing it and feeling its gravity for 8 minutes - the information about its disappearance couldn't reach us faster than light speed.
