Solution

The correct option is A Zero
Chemical reaction
$A ⟶ p r o d u c t$
Rate law states that
$R a t e l a w = k [A]^{o}$
A zero order reaction is the one in which the rate is proportional to the zeroth power of the concentration. The total pressure will not affect the pressure of the gas on the surface cannot change by increasing the pressure
Therefore it is a zero order reaction.
