Answer;
is balanced by the inward gravitational pressure.
Explanation; The outward pressure of hot gas in the Sun is balanced by the inward gravitational pressure. The sun's output is so stable because of hydrostatic equilibrium. The outward pressure of hot gas comprising the sun exactly balances the force of gravity which tries to make the sun grow smaller. When the star such as the sun shrinks, the core pressure and temperature increase and this increases the pressure, resisting the shrinkage. On the other hand, when the star swells, the core pressure and temperature drop and reduce the pressure, and gravity makes the star stop swelling.
