Correct answer
B
Step-by-step explanation
by mass means :
in 100 g solution.
in solution.
$\begin{aligned}
& \mathrm{m}_{\text {solution }}=\frac{100 \times 30}{75} \mathrm{~g} \\
\because \quad & \mathrm{~V}_{\text {sol }}=\frac{\mathrm{m}_{\text {sol }}}{\mathrm{d}_{\text {sol }}}=\frac{100 \times 30}{75 \times 1.25}=32 \mathrm{~mL}
\end{aligned}$
