Answer:

A. 6.25 ml

Explanation:

In 20 ml of methyl, 25% of the solution is methyl alcohol. This means that 5 ml of the content is pure methyl alcohol. If we take 5 ml of liquid from the solution, this means that 6.25 ml is the volume.

25 % of the 20 ml solution is 5 ml.

(20 ml) (0.25)  = 5 ml.

25% of 5 ml is 1.25 ml.

(5) (0.25) = 1.25 ml

We need to add both to get the volume.

5 ml + 1.25 ml = 6.25 ml
