Which of the following is correct about self-pollination?

• It leads to increased genetic diversity within a plant population

• It involves the transfer of pollen from one flower to another flower of a different plant

• It occurs when pollen is transferred from the anther to the stigma of the same flower or another flower on the same plant

• It requires the assistance of external agents like insects, wind, or animals
