Goryan [66]

Answer:

c. A bacterial cell that lacked receptors on its surface for that antibiotic

Explanation:

If the bacteria lacks the receptors on its surface meant for that antibiotic then it will be best defense for the survival of that bacteria. It is receptors which interact with the antibiotic so as to permit it inside the cell. Therefore, in the absence of receptors, it doesn't matter how much antibiotic is lying in the external environment of that bacteria, the antibiotic will not be able to enter the bacterial cell to kill it. Hence, the bacteria will be able to survive easily.
