Answer:

  • c) Turmeric.
  • d) Juice of China rose petals.

Explanation:

Turmeric and Juice of China rose petals are natural indicators above.

But,

  • Litmus paper and phenolphthalein are artificial or man made indicators.

Working:

  • Litmus paper turns red litmus into blue when is putted in alkaline solution.
  • Phenolphthalein is a colourless liquid which turns pink in colour when it is added to base.
