Answer: It is a selective and differential medium.
Explanation: Selective medium is used to select the growth of certain bacteria whilst inhibiting the growth of another by preparing a medium with ingredients that will only select a specific growth of intended microbe. When closely related bacteria had been selected, they can further be differentiated by the way they utilize the medium. In this case staphylococcus aureus was first selected using sodium chloride with which only this bacteria can tolerate i.e halophilic (strives in salty environment). It was also further differentiated by its ability to ferment sugars changing the colour of the pH indicator chemical.
