Answer 1

The correct option is B Transfer of pollen grains from the anther to the stigma of another flower of the same plant.

Geitonogamy is the transfer of pollen grains from the anther to the stigma of another flower of the same plant.

Transfer of pollen grains from the anther to the stigma of a different plant belonging to the same species is called Xenogamy.

Transfer of pollen grains from the anther to the stigma of the same flower is called autogamy.

Transfer of pollen grains from the anther of one species to the stigma of another species is unlikely to result in fertilisation in most cases.
