Answer:

Option b. Lowering the pH to kill pathogenic bacteria is correct answer.

Explanation:

bacterial motors are sensitive to pH.  By decreasing the pH bacterial motors stops working. This was identified in a new research.  But, with the weak acids and a lower internal pH they slow and ultimately stop moving (became dead).
