Solution

The correct option is B Both statements are true but Statement -II is not correct explanation of Statement - I
For a zero-order reaction, $t_{1 / 2} = \frac{[A]_{0}}{2 k} .$
Hence, if in a zero order reaction, the concentration of the reactant is doubled, the half-life period is also doubled.
The rate of a zero-order reaction is independent of the concentration of the reaction. The reaction proceeds at constant rate throughout.
Thus, both statements are true. but Statement -II is not correct explanation of Statement - I.
