Answer:
B.Four hydrogen nuclei combine into one helium nucleus.
Explanation:
Mass energy which is stored in a matter itself can be very powerful. A small amount of mass can result in a very large amount of energy as the speed of light is very large.
If we consider the two elements hydrogen and helium, a hydrogen nucleus is made of one proton and a helium nucleus is made of two protons and two neutrons.
The mass of hydrogen is 1.6726 x 10–27 kg, and the mass of helium is 6.6465 x 10–27 kg.
Four hydrogen nuclei combine into one helium nucleus would lead to decrease of total mass, and thus a release of energy such that the number of particles involved remains same.
