A. If both Assertion \& Reason are True \& the Reason is a correct explanation of the Assertion.
\( \mathrm{P} \)
B. If both Assertion \& Reason are True but Reason is not a
W correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion \& Reason are False.
Assertion :- If three polarisers are arranged such that the axis of any two successive polarisers make equal angle with each other. If unpolarised light of intensity \( \mathrm{I}_{0} \) incident on first polariser then intensity of emergent light after \( 3^{\text {rut }} \) polariser is \( \frac{I_{0}}{8} \), If angle between them is \( 45^{\circ} \).
Reason :- Each time intensity becomes 50\% by Malus law.
(1) A
(2) B
(3) \( \mathrm{C} \)
(4) \( \mathrm{D} \)
