i think its option B

Answer 2

Option A . Microspore wall.

Explanation:

When mMicrospore mother cell undergoes meiosis , 4 microspores are formed which develop into pollen grains.

Each Microspore enlarges and develops a two layered wall, Exine ( outer wall) and Intine ( inner wall).

Exine is further made of two layers : Ektexine or Sexine (outer) and Endexine.

Extexine is made of Tactum, baculum and foot layer.

Tactum is responsible for providing a characteristic design over the surface of pollen grain.
