Litmus, a well-known acid-base indicator, is derived from:

Options

  1. AFungi
  2. BLichens
  3. CBacteria
  4. DTermite

Correct answer

B. Lichens

Step-by-step solution

Litmus, a natural dye used as an acid-base indicator, is derived from lichens. Lichens are symbiotic organisms composed of a fungus (usually an ascomycete) and an algae or cyanobacterium. Litmus is extracted from certain species of lichens and changes color depending on whether it is exposed to an acidic or basic environment.
