In case of parallel reaction, A is a reactant, in forward reaction condition concentration of reactant decreases with time whereas concentration of both the products increases with time.

$\\\text{Rate of formation of }\mathrm{B}=\left[\frac{d[B]}{d t}\right]=K_1[A]\\ \\\text{Rate of formation of} \; \mathrm{C}=\left[\frac{d[C]}{d t}\right]=K_2[A]$

Since as per question $K_2 \ggg K_1$ thus at a particular time concentration of $[\mathrm{C}]>[\mathrm{B}]$

Thus, in concentration $\mathrm{v} / \mathrm{s}$ time curve line with respect to $\text{C}$ lies above $\text{B}$ .
