In an Earlier Era, Some Scientists Suggested That the Energy

In an earlier era, some scientists suggested that the energy of the Sun comes from meteorites (or, more properly, meteoroids) falling into it and converting their falling motion into heat. Which of the following is part of the argument that shows this mechanism will not work?

A) the antimatter in the Sun would make the meteorites explode before they could do this
B) a mass of meteorites equal to the mass of the Earth would have to fall in every century
C) the meteorites would eventually increase the mass of the Sun and change the orbits of the planets
D) since the Sun is made of gas, it does not have enough gravity to pull in meteorites
E) more than one of the above
