(i) `N_(2)(g)+O_(2)(g)hArr2NO(g), K_(1)`
(ii) `((1)/(2))N_(2)(g)+((1)/(2))O_(2)(g)hArrNO(g), K_(2)`
(iii) `2NO(g)hArrN_(2)(g)+O_(2)(g), K_(3)`
(iv) `No(g)hArr((1)/(2))N_(2)(g)+((1)/(2))O_(2)(g), K_(4)`
Correct relation between `K_(1),K_(2),K_(3) "and" K_(4)` is//are:
A. `K_(1)xxK_(3)=1`
B. `sqrtK_(1)xxK_(4)=1`
C. `sqrtK_(3)xxK_(2)=1`
D. None
