Solution

The correct option is B
23.07 %

Volume of solute (ethyl alcohol) = 30ml

Volume of solvent (water) =100ml

Total volume of solution=30 + 100 = 130ml

Volume by volume % = $\frac{v o l u m e o f s o l u t e}{v o l u m e o f s o l u t i o n} \times 100$ = $\frac{30}{130} \times 100$ = 23.07%
