Postzygotic isolation refers to the mechanisms that prevent hybrid offspring from surviving or reproducing. If hybrids have reduced fitness or are sterile, this will lead to selection against hybridization. Prezygotic isolation mechanisms prevent hybridization from occurring in the first place, while geographic barriers and temporal isolation can also contribute to reproductive isolation but do not necessarily lead to selection against hybridization. Therefore, option B is the best choice.
