The correct option is C Non-motile as there is no flagellated stage in the life cycle of angiosperms
The male gametes of angiosperms consist of two sperm cells within a pollen grain or a pollen tube. They are derived from a single generative cell, which is formed as the smaller cell by unequal cell division in the microspore after meiosis. The gametes formed will be non-motile as there is no flagellated stage in the life cycle of angiosperms.
