Answer

Brief Explanations:

  1. Nuclear fusion: It combines light - weight nuclei to form a heavier nucleus, releasing a large amount of energy. It requires high temperatures and pressures (high - energy input initially to overcome electrostatic repulsion between nuclei), but overall has a high energy output.
  2. Nuclear fission: It splits a heavy - weight nucleus into two or more lighter nuclei, also releasing a large amount of energy. It can be initiated by neutron bombardment and has a high energy output.
  3. Analysis of options:
    • Option a: Fusion requires high energy input, but fission can be initiated with a neutron and doesn't always require extremely high energy input like fusion.
    • Option b: Both fusion and fission have by - products. For example, in fission, radioactive by - products are often produced.
    • Option c: Both processes release a large amount of energy, so they have a high energy output.
    • Option d: Only fission involves large atoms breaking into smaller atoms; fusion combines small atoms.

Answer:

C. They both have a high energy output.
