Solution

The correct option is A

P- Autogamy, Q- Geitonogamy, R- Xenogamy


P represents Autogamy, i.e, the transfer of pollen grains from the anther to the stigma of the same flower. Geitonogamy is the transfer of pollen grains from the anther to the stigma of another flower of the same plant and is labelled Q in the image. Xenogamy or allogamy represented by R, is the transfer of pollen grains from anther to the stigma of a different plant.
