Correct answer: B

Option B : (B), (C) and (D) only

Explanation : Lateral meristems are the meristems that add to the width or girth in a process known as secondary growth. They are responsible for the secondary growth in plants and are found parallel to the sides of the plants.

  1. 1. Axillary buds (A) are not lateral meristems; they are capable of forming branches or flowers.
  2. 2. Fascicular vascular cambium (B) is a type of lateral meristem. It contributes to secondary growth and produces secondary vascular tissues.
  3. 3. Interfascicular cambium (C) is also a type of lateral meristem. It also contributes to secondary growth in the stem.
  4. 4. Cork cambium (D), also called phellogen, is a lateral meristem and it produces the cork, a part of the protective outer layer (periderm) in stems and roots.
  5. 5. Intercalary meristem (E) is not a type of lateral meristem but rather a type of apical meristem located at the base of leaves or internodes on a plant stem, which is involved in primary growth and elongation of the plant.

Therefore, the correct answer is option B : Fascicular vascular cambium (B), Interfascicular cambium (C) and Cork cambium (D) only.
