D

When pollen grains from the stamen of a flower is transferred to the stigma of the same flower or a different flower in the same plant, it is called self-pollination. When pollen from the stamen of one flower is transferred to the stigma of another flower in a different plant of the same species, it is called cross-pollination. Pollination is successful (leading to fertilisation) only if it occurs within the flowers of the same species.
