Detailed Solution

Concept: Pollination is the process of transfer of pollen from the anther to the stigma.

Pollination can be of different types depending on the location of the anther and the stigma.

Geitonogamy is pollination in the same flower.
Xenogamy is the type of pollination in which pollen is transferred to the anther of one flower to the stigma of another flower of a different plant.

In geitonogamy inbreeding depression will occur as genes are shuffled within the same gene pool.

Hence the correct option is B.
