The correct answer is C, $H_{2}SO_{4}$.<br /><br />Litmus is a pH indicator that changes color depending on the acidity or basicity of a solution. When litmus is added to an acidic solution, it turns red. When litmus is added to a basic solution, it turns blue.<br /><br />Among the given options, $H_{2}SO_{4}$ (sulfuric acid) is an acidic substance, so it would turn litmus red. The other options, $Sr(OH)_{2}$ (strontium hydroxide), $H_{2}O$ (water), and $SrSO_{4}$ (strontium sulfate), are either neutral or basic substances, so they would not turn litmus red.
