$[R]$ vs $time$ is a decreasing curve,while $[P]$ vs $time$ is an increasing curve.

(C) For a chemical reaction $R \to P$:$1$. The concentration of the reactant $[R]$ decreases over time as it is consumed to form the product.$2$. The concentration of the product $[P]$ increases over time as it is formed from the reactant.$3$. Therefore,the graph of $[R]$ versus $time$ shows a downward slope (decreasing curve),and the graph of $[P]$ versus $time$ shows an upward slope (increasing curve).
