Answer:
B. MacConkey is both a differential and a selective medium.
Explanation:
Selective media contain the ingredients that allows for the growing of specific microbes while inhibiting the others.
For example MacConkey media facilitate the growth of gram negative bacteria and inhibit the growth of gram positive bacteria. That why E. coli and P. mirabilis grew on the media because these are gram negative and S. saprophyticus does not grew being gram positive.
Differential media allow to differentiate between selected microbes by visual observation.
For Example MacConkey media differentiate between organisms that can ferment lactose to the organisms that can't ferment it. That why E. coli appeared pink on the media because it can ferment lactose while P. mirabilis appears colorless because it usually cannot ferment lactose.
