In Flowering Plants, the Style Separates the Site of Pollen

In flowering plants, the style separates the site of pollen reception from the ovules to be fertilized by a distance of up to 10 cm. What might be the adaptive significance of this distance?

A) It allows pollen tube competition to play out over distances requiring significant growth and interaction with the style.
B) It keeps ovules safely away from fungal spores and other pathogens that may also germinate on the style and attempt to access the ovaries.
C) It may elevate the receptive surface away from the stamens to prevent self-fertilization.
D) It allows the maternal sporophyte a degree of selectivity over the male genotypes involved in fertilization, as in self-incompatibility.
