Respuesta :
the nuclear fusion reaction occurs just outside the inner core, creating an explosive force that keeps the star 'inflated.' Gravitational pull toward the star's center of mass keeps enough pressure on the core to keep the heat and pressure necessary for fusion to occur.

Answer:
A. Nuclear fussion reactions.
B. Generates an internal pressure that try to expand the star.
C. Gravity force and internal pressure.
Explanation:
In a star there is a balance between gravity force, that attracts the stellar gas towards the center and compressing it, and the pressure due to nuclear fusion reactions that occur within the star, that acts in the opposite direction to gravity trying to expand the star. Therefore, the star is in equilibrium and adopts a stable spherical shape.
