The correct answer is B. Litmus.
Explanation:
A natural indicator is a substance that changes color in response to a change in pH and is derived from natural sources.
Litmus: Derived from lichens, litmus is a natural pH indicator that turns red in acidic solutions and blue in basic solutions.
Methyl orange and Phenolphthalein are synthetic indicators. Methyl orange changes color from red to yellow as the pH changes from acidic to neutral, and Phenolphthalein changes from colorless to pink as the pH becomes basic.
So, among the options provided, only litmus is a natural indicator.
