Read the passage given below and answer the following questions.

The cells of the sporogenous tissue undergo meiotic cell divisions to form microspore tetrads due to callose. As each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad. Each one is a potential microspore mother cell. The process of formation of microspores from a pollen mother cell through meiosis is called microsporogenesis. The pollen grains (n), as they are formed, are arranged in a cluster of four cells- the microspore tetrad i.e., tetrahedral due to callose. As the anthers mature and dehydrate, the microspores dissociate from each other due to callase and develop into pollen grains (n).

Study of pollen grains of following plant is

A) Palynology

B) Palaeontology

C) Palaeobotany

D) None of these
