Let’s check out your problem:

$$\left[H^{+}\right]=10^{-\mathrm{pH}}$$$\newline$$\mathrm{pH}$ is a measure of the hydrogen ion concentration, $\left[\mathrm{H}^{+}\right]$, measured in moles per liter, of a solution. Solutions with a high concentration of hydrogen ions have a low $\mathrm{pH}$ and solutions with a low concentration of hydrogen ions have a high $\mathrm{pH}$. The relationship between $\left[\mathrm{H}^{+}\right]$and $\mathrm{pH}$ is shown in the equation. What is the effect on $\mathrm{pH}$ if the hydrogen ion concentration is multiplied by $10$ ?$\newline$Choose $1$ answer:$\newline$(A) The $\mathrm{pH}$ increases by $1$ .$\newline$(B) The $\mathrm{pH}$ is multiplied by $10$.$\newline$(C) The $\mathrm{pH}$ is divided by $10$ .$\newline$(D) The $\mathrm{pH}$ decreases by $1$ .
