During which of the following methods are Bulbils produced?

  1. Seed sowing

  2. Tissue culture

  3. Vegetative propagation

What is the cultivation medium required for tissue culture called?

  1. Nutrient Broth

  2. Basal medium

  3. Potato dextrose broth (PDB)

  4. Sabrauds agar


Correct Option: B
