Why Might Candida Albicans Become Pathogenic in an Individual Receiving

Why might Candida albicans become pathogenic in an individual receiving antibacterial medications?

A) This fungal organism can actually utilize the destroyed bacterial cells as a nutrient source and begin to multiply out of control.This can cause a pathogenic state.
B) This is an opportunistic pathogen not normally found in normal microbiota.As such,when the bacterial normal microbiota is wiped out by broad-spectrum antibacterial drugs,this opportunist can adhere to and colonize the area left behind.
C) This is a usual member of the normal microbiota.However,when the bacterial members of the normal microbiota are wiped out by a broad-spectrum antibacterial drug,this fungal cell type has little to no competition for resources in the affected area.As such,it quickly overgrows and can cause a pathogenic state.
D) This is a protozoan species and part of the normal microbiota.When the bacterial members of the normal microbiota are wiped out by a broad-spectrum antibacterial drug,this protozoan cell type has little to no competition for resources in the affected area.As such,it quickly overgrows and can cause a pathogenic state.
