Assertion :- A beam of charged particles is
\( P \) employed in the treatement of cancer.

W.
Reason :- Charged particles on passing through a material medium lose their energy by causing ionization of the atoms along their path.
(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.
