For a first order reaction $\mathrm{A} \rightarrow$ products, the plot of $\ln \left(\frac{[\mathrm{A}]_{\mathrm{t}}}{[\mathrm{A}]_{0}}\right)$ vs time, where $[\mathrm{A}]_{0}$ and $[\mathrm{A}]_{\mathrm{t}}$ to concentration at time $=0$ and t respectively, is
(a)A straight line with a positive slope passing through origin
(b)A straight line with a negative slope passing through origin.
(c)An exponential curve asymptotic to the time axis
(d)A curve asymptotic to the $\ln \left(\frac{[\mathrm{A}]_{\mathrm{t}}}{[\mathrm{A}]_{0}}\right)$
