Column I shows four situations of standard Young's double slit arrangement with the screen placed far away from the slits S $_1$ and S $_2$. In each of these cases, S $_1$ P $_0$ = S $_2$ P $_0$, S $_1$ P $_1-$ S $_2$ P $_1$=$\lambda/4$ and S $_1$ P $_2-$ S $_2$ P $_2$=$\lambda/3$, where $\lambda$ is the wavelength of the light used. In the cases B, C and D, a transparent sheet of refractive index $\mu$ and thickness t is pasted on slit S $_2$. The thickness of the sheets are different in different cases. The phase difference between the light waves reaching a point P on the screen from the two slits is denoted by $\delta$(P) and the intensity by I(P). Match each situation given in Column I with the statement(s) in Column II valid for that situation:

	Column I		Column II
(A)		(P)	$\delta ({P_0}) = 0$
(B)	$(\mu-1)t=\lambda/4$	(Q)	$\delta ({P_1}) = 0$
(C)	$(\mu-1)t=\lambda/2$	(R)	$I({P_1}) = 0$
(D)	$(\mu-1)t=3\lambda/4$	(S)	$I({P_0}) \gt I({P_1})$
		(T)	$I({P_2}) \gt I({P_1})$
