A block of mass 2kg is kept over a block of mass 8 kg as shown in the figure. A force F = 14Nacts on the upper block. Match the physical quantities from List I with those in List II and select the correct answer using the code given below the lists. All values are in S.I. units:

	List-I		List-II
(P)	Acceleration of block 2 kg	(1)	10
(Q)	Acceleration of block 8 kg	(2)	1
(R)	Friction action between the blocks	(3)	12
(S)	Friction acting between lower block and ground	(4)	$\frac{1}{4}$

	P	Q	R	S
(A)	4	2	1	3
(B)	2	4	1	3
(C)	1	2	3	4
(D)	2	4	3	1
