Explanation:

Step1: Recall pH scale properties

The pH scale ranges from 0 - 14. Acids have pH values less than 7, bases have pH values greater than 7, and neutral substances have a pH of 7.

Step2: Classify given substances

Vinegar is an acid, water is neutral (pH = 7), and soap solution is a base (pH > 7).

Step3: Determine lowest pH

Since acids have lower pH values than neutral and basic substances among the three, vinegar will have the lowest pH.

Answer:

A. Vinegar
