Which of the following is true about fusion?
A
Fusion happens in atomic bombs
B
Fusion produces radioactive waste
C
Fusion happens on the sun and stars
D
Fusion happens at nuclear power plants
Explanation: 

Detailed explanation-1: -Assertion :The nuclear fusion reaction releases less energy than the fission reaction. Reason: The nuclear fusion reaction takes place in the sun and other stars.

Detailed explanation-2: -In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

Detailed explanation-3: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.

Detailed explanation-4: -The light and heat from stars is made by a process called nuclear fusion. Fusion happens when 2 atoms are forced together to form a heavier atom. This creates a lot of energy. However, fusion can only occur at the incredibly high temperatures and pressures found in the centre of stars.

Detailed explanation-5: -The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion. Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium.
