In which part of the sun do gases heat up and rise and then cool down and sink? convective zone inner core photosphere radiative zone

Answer is Convective zone.

The Sun is made of several layers of hot gases. The Core, the first layer of Sun’s interior where energy is formed though nuclear fusion. From the core, energy moves outward toward the Sun’s surface and surrounding atmosphere. The energy moves through several layers. The energy moves out from the core through the Radiative zone. The Sun’s next layer is the Convection zone. The convective zone is the outermost layer of the Sun’s interior. Through convection process energy moves from the inner parts of the Sun to the outer part of the Sun. in this zone gases heat up and rise and then cool down and sink. The rising and sinking of gases is called convection.
