What is the process of transfer of pollen from the anther to the stigma of a flower ?

Pollination

The correct answer is Option (3) – Pollination

Insects visit flowers and carry away pollen on their bodies. Some of the pollen lands on the stigma of a flower of the same kind.

The transfer of pollen from the anther to the stigma of a flower is called pollination.

If the pollen lands on the stigma of the same flower or another flower of the same plant, it is called self-pollination.

When the pollen of a flower lands on the stigma of a flower of a different plant of the same kind, it is called cross-pollination
