Answer:
Option B is correct.
Explanation:
Carbohydrate fermentation test; its main purpose is to know if a bacteria can ferment a specific carbohydrate or not. The test can be used for distinguishing bacterial species.
When fermentation of carbohydrate occurs, gaseous acids are produced. This production of the acid lower the pH of the medium undergoing the test, which can be detected by the color change of the pH indicator.
The Color changes only when sufficient amount of acid is produced. Phenol red can easily detect single acid production but METHYL RED NEED MORE ACID.
