You're right, the answer is "A. Add 15 mL of distilled water to 5 mL of pure lemon juice". The solution of lemon juice is 20 mL and 5 is 25% of it.

Answer:

The correct answer would be option A.

25 percent solution of lemon juice means that 25 parts out of 100 are of the lemon juice in a solution.

If we add 15 milliliters of distilled water to 5 milliliters of pure lemon juice then the total amount of solution would be 20 milliliters.

Hence, the concentration of lemon juice would be equal to [tex]\frac{5}{20}\times100[/tex] ⇒ 25 percent.

Thus, option A would be the correct answer.
