At constant temperature, the equilibrium constant `(K_(p))` for the decomposition reaction
`N_(2)O_(4) hArr 2NO_(2)`
is expressed by `K_(p)=4x^(2)p//(1-x^(2))`, where p=pressure x= extent of decomposition. Which of the following statements is true?

Options

A. `K_(p)` increases if pressure is increased
B. `K_(p)` increases if x is increased
C. `K_(p)` decreases if pressure is decreased
D. `K_(p)` would remain same with change in pressure.
