Since light takes 8 minutes to travel from the Sun to the Earth, the Earth is one Astronomical Unit (AU) away from the Sun. Therefore, the distance from the Sun to Neptune can be calculated by finding how many AUs are between them. Given that it takes over 4 hours (240 minutes) for light to travel from the Sun to Neptune, the distance between them is approximately 30 AUs (240 divided by 8). Therefore, the correct answer is B) 30 Astronomical Units.
