Which of the following is true about nuclear fusion?
it produces less energy than nuclear fission.
it is easy to implement.
it has the ability to occur easily in everyday life.
it produces more energy than nuclear fission.

D.Nuclear fusion produces more energy than nuclear fission.

Explanation:

Nuclear fission:It is a process in which a heavy unstable nuclei split into two or more than two nuclei of mass slightly less than the original mass and a large energy released in this process.

The difference in the mass of product and reactant is called mass defect and convert into energy during fission.

Nuclear fusion: It  is a process in which two or more light nuclei combined together and form a nuclei of mass slightly less then mass of sum of reactants and huge amount of energy released during this process.

In this process, difference in mass of reactant and product convert into energy.

But the energy released in fusion is greater than the energy  release in fission process because binding energy operates as the number of   nucleon increase.

Hence, option D is true.

D.Nuclear fusion produces more energy than nuclear fission.

b) mutualism

hope this : )

the answer is a and have a great day
