Options:

A conc. of $\mathrm{x}$ is kept constant and conc. of $\mathrm{y}$ is halved
B conc. of both $\mathrm{x}$ and $\mathrm{y}$ is doubled
C conc. of $\mathrm{x}$ is doubled and conc. of $\mathrm{y}$ is kept constant
D conc. of $\mathrm{y}$ is doubled and conc. of $\mathrm{x}$ is halved

The correct answer is: conc. of $\mathrm{x}$ is doubled and conc. of $\mathrm{y}$ is kept constant

$\mathrm{r}=\mathrm{k}(\mathrm{x})(\mathrm{y})$
Of $\mathrm{x}$ is doubled and $\mathrm{y}$ remains constant the rate is doubled.
