Answer:
B Eight light-minutes
Explanation:
In the case when the distance separated earth and the sun so here we orbit the sun for a 150 million km distance and the light moves would be 300,000 kilometers per second

= 500 seconds
This 500 seconds represent 8 minutes and 20 seconds
Hence, option B is correct
