The correct option is B.
Nuclear fission and fusion are two different types of nuclear reactions, through which energy may be obtained. Nuclear fission involves the splitting of a molecule into two different part in order to generate energy while nuclear fusion reaction involves the joining together of two elements in other to form one product. Nuclear fission generate much radioactive waste than nuclear fusion. The radioactive waste that is obtainable during nuclear fusion is less than 1% of that produce by nuclear fission.

Explanation:
a) Two balls are at a distance of L/2 from the axis of rotation and one block at the center. ( center of rod).
therefore,
b) two balls at a distance L/4 at the from the axis and 1 ball at a distance 3L/4 from the from the axis.

The second law of thermodynamics states that whenever energy changes occur, DISORDER always increases.
The formula for potential energy is PE=mgh
It can have that high of a potential energy if it's relative height what super high.
