B Correct answer
Explanation

If you traveled at light speed away from the Sun, you would continue to see the Sun's light for as long as you traveled because photons emitted at different times would still reach you. However, this is a thought experiment - nothing with mass can reach light speed. The question asks for an intuitive understanding, and 30 years represents a reasonable timespan for solar visibility becoming negligible in an imagined scenario.
