For the reaction $\mathrm{P}+\mathrm{Q}+\mathrm{R} \rightarrow \mathrm{S}$, experimental data for the measured initial rates is given below.

Expt.	Initial conc. P (M)	Initial conc. Q (M)	Initial conc. R (M)	Initial rate $(\mathrm{Ms^{-1}})$
1	0.2	0.5	0.4	$8.0 \times 10^{-5}$
2	0.4	0.5	0.4	$3.2 \times 10^{-4}$
3	0.4	2.0	0.4	$1.28 \times 10^{-3}$
4	0.1	0.25	1.6	$4.0 \times 10^{-5}$

The order of the reaction with respect to P, Q and R respectively is:

(a)2, 2, 1

(b)$2,1,2$

(c)2, 1, 1

(d)1, 1, 2
