MCQ
Nuclear fusion reactions cannot be harnessed for productive applications because:
  • A
    These reactions require very high temperature and are controllable.
  • ✓
    These reactions require very high temperature and are uncontrollable.
  • C
    These reactions require very low temperature and are uncontrollable.
  • D
    These reactions require very low temperature and are controllable.
✓

Answer

Correct option: B.
These reactions require very high temperature and are uncontrollable.

Fusion reaction is the combining of atom to form heavier nuclei. Fusion reaction requires high temperature. God fusion to occur on earth a, we need a temperature of at least $100$ million degree Celsius. It is also an uncontrollable reaction.
