Assertion :- A particle at rest breaks into two particles of different masses. They fly off in
\( P \) different directions. Their de Broglie wavelengths

W. will be different.
- Reason :- Their speed will be different.
- (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.
