Solution a is the most acidic.
In a pH scale of 1 to 14, the smaller the pH is, the more acidic is. In opposite, the higher the pH is, the more alkaline it is. We call substances with pH below 7 as acid, and above 7 as alkali, while 7 as neutral.
Therefore, comparing the 4 solutions, solution a has the lowest pH, 3, so it is the most acidic.

<span>A food preservation method in which microorganisms metabolize components of a food is called </span>fermentation.
When the food is going on fermentation, there are good bacteria over there that will inhibit other bacteria to grow on that food. Fermentation also able to made the pH more acid, making the area is not suitable for bacterial growth.
