Solution

The correct option is B The reaction is zero order reaction
$r = K [A]^{0}$ .
Since units of rate constant are same as the units of rate of reaction it can be
a zero order reaction.The plot of concentration vs time corresponds to a horizontal line parallel to x-axis as it is independent of the concentration.
