The Balance of Energy in the Solar Interior Means That

The balance of energy in the solar interior means that:

A) energy production rate in the core equals the rate of radiation escaping the Sun's surface
B) the source of energy in the core is stable and will sustain the Sun for millions of years
C) the outer layers of the Sun absorb and re-emit the radiation from the core at increasingly longer wavelengths
D) radiation pressure balances the weight of the overlying solar layers
E) the core of the Sun has higher pressure than the outer layers
