A. Evaporation
B. Fission
C. Fusion
D. Oxidation

Answer 1

The process that powers stars is C)fusion

Answer 2

Answer: The correct answer is Option C.

Step-by-step explanation:

A star is defined as a fixed point in the night sky which illuminates and is very large. the primary element present in stars is Hydrogen and it continuously changes to helium by a process known as Nuclear fusion reaction. This process releases a huge amount of energy.

Nuclear fusion reaction is defined as the combination of lighter nuclei to form a heavy nuclei. In Stars, hydrogen atoms combine to form a helium atom.

The reactions which takes place in stars follows a series of equations:

`_1^1\textrm{H}+_1^1\textrm{H}\rightarrow _1^2\textrm{H}+_(+1)^0\textrm{e}+\text{energy}\\\\_1^2\textrm{H}+_1^1\textrm{H}\rightarrow _2^3\textrm{He}+\text{energy}\\\\_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_(+1)^0\textrm{e}+\text{energy}`

Overall reaction for the above series of reactions is given by:

`4_1^1\textrm{H}\rightarrow _2^4\textrm{He}+2_(+1)^0\textrm{e}+\text{energy}`

Hence, the correct answer is Option C.
