The sun is constantly radiating energy and yet its surface temperature is nearly constant at $6000^{\circ} \mathrm{C}$. The constancy of solar temperature is due to :

A
fission
B
radioactivity
Correct answer
C
fusion
D
black hole evaporation

Solution

The correct answer is option (C).

Hence, the correct answer is option: 'C'.
