\mathrm{\begin{aligned} & A(g) \longrightarrow 2 P(g) \\ & \text { (0.5M) After completion (1M) } \\ & \mathrm{k}=0.5 \mathrm{Ms}^{-1} \\ & \end{aligned}}

By unit, it is clear that reaction is zeroth order.

\mathrm{\begin{aligned} & x=k t \\ & t_{\text {competion }}=\frac{a}{k}=\frac{0.5}{0.5}=1 \mathrm{sec} \end{aligned}}

 Correct Option: C
