Consider folllowing reaction at 300 K :
`N_(2)O_(5)(g)hArrN_(2)O_(5)(g)+O_(2)(g)` `K_(c)=5`
`N_(2)O_(5)(g)hArrN_(2)O(g)+O_(2)(g)` If 4 moles `N_(2)O_(5)` is kept in 1 L, Container to attain equilibrium and at equilibrium 5 moles of `O_(2)` are produced, then at equilibrium 5 moles of `O_(2)` are produced, then at equilibrium moles of `N_(2)O_(3)` will be :
A. 1
B. 3
C. 2
D. 4
