Solution
Explanation:
Increasing the pH of tomato soup from low acidic to neutral kills the bacteria faster as spore formation of bacteria doesn't take place at neutral conditions. Tomatoes and tomato-based foods contain high levels of acid and relax the lower esophageal sphincter muscles in the same way chocolate does. Hence, the correct option is (C).
