SI unit of velocity gradient \mathrm{\left(\frac{d V}{d x}\right)} and decay constanct \mathrm{\left(\lambda=\frac{\ln (2)}{T_{1 / 2}}\right)} is 
\mathrm{\begin{aligned} &(\text { second })^{-1} \\ &\therefore\left[\frac{d v}{d x}\right]=[\lambda]=\left[T^{-1}\right] \end{aligned}}
The correct option is (1)
