• B. Sun is $8$ light minutes away from the earth

Answer 1

The correct option is B

Sun is $8$ light minutes away from the earth

Light travels at a speed of $300,000km{s}^{-1}$ and the distance between Earth and the sun is $150$ million km. Thus it takes nearly $8$ minutes for light from the sun to reach Earth.
