There is very little hydrogen or helium in the inner part of the solar system today.We believe the reason for this is that:
A) all the light elements went into the formation of the Sun itself and little were left over for the rest of the solar system.
B) the intense radiation from the early Sun drove the light elements out of the inner solar system.
C) heavier elements were attracted in from the outer part of the solar system, displacing the light elements that were originally in the inner part.
D) the light elements underwent chemical reactions and were locked up in chemicals in the inner solar system.

The intense radiation from the early Sun is believed to have driven the light elements such as hydrogen and helium out of the inner solar system. This is supported by observations of the composition of meteorites, which show that the inner solar system contains much less hydrogen and helium than the outer solar system. Additionally, models of the formation of the solar system support this idea. Therefore, option B is the best choice as it provides the most plausible explanation for the lack of light elements in the inner solar system.
