Assertion : In hydrogen atom there is only one electron, but its emission spectrum shows many
\( P \) lines.

W.
Reason : In a given sample of hydrogen, there
- are many atoms, each containing one electron; hence many electrons in different atoms may be in different orbits, so many transitions from higher to lower orbits are possible.

(3) \( \mathrm{C} \)
(4) D
(A) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
(B) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
(C) Assertion is correct, but reason is wrong statement.
(D) Assertion is wrong, but reason is correct statement.
