Assertion :- Two different radioactive substances have initially same number of nuclei. Their decay
\( P \) constants are \( \lambda_{1} \) and \( \lambda_{2}\left(\lambda_{1}\right) \). Then initially first
- radioactive substance decays at faster rate.
- Reason :- Half life of first radioactive substance
- is lesser than second.
- (1) A
(2) B
(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.
