Answer 1

Answer:

III and IV statement is correct regarding nuclear fusion.

Explanation:

• No Nuclear fusion is not a chain reaction, because fusion energy production is not based on a chain reaction, as is fission.
• Nuclear fusion is easy to control.
• The fusion requires both extremely high temperatures to give hydrogen atoms enough energy to overcome repulsion between the protons.
• In nuclear fusion, a large number of radioisotopes are produced and hence large nuclear waste is left.
