Solution
The correct option is B meiotic
Pollen grain is the male gametophyte. They are haploid and are developed from microspores. Microspores are produced in the microsporangium. Each sporogenous cell can undergo meiosis to produce microspore tetrad or can act as a microspore mother cell or pollen mother cell (PMC). The process is called microsporogenesis.
One meiotic division in a pollen mother cell gives rise to 4 microspores, which develop into 4 pollen grains, therefore 25 meiotic divisions are required to produce 100 pollen grains.
Thus, pollen grains are formed by meiotic division in locules of anthers.
