A hydrogen bomb is a

controlled nuclear fission

uncontrolled nuclear fision

uncontrolled nuclear fusion

controlled nuclear fusion

Assertion (A) : Hydrogen bomb is more powerful than atomic bomb. Reason (R) : In hydrogen bomb, fusion reaction is initiated.

If both `(A)` and `(R)` are correct , and `(R)` is the correct explanation of `(A)`

If both `(A)` and `(R)` are correct, but (R) is not the correct explanation of `(A)`

If `(A)` is correct, but `(R)` is incorrect.

If `(A)` is incorrect, but `(R)` is correct.

Statement 1 : Hydrogen bomb involves not only fusion but also fission reactions to start the fusion whereas atom bomb involves only fission. Statement 2 : Though energy liberated per fusion is smaller than energy liberated per fission, yet hydrogen bomb is more powerful than atom bomb.
