Answer:

The correct answer is option c."A bacterial cell that lacked receptors on its surface for that antibiotic".

Explanation:

There are different mechanisms by which bacteria can get antibiotic resistance. One common mechanism is that the bacteria changes the site or changes the receptor that is recognized by the antibiotic to work. Taking into account this adaptation, a bacterial cell that lacked receptors on its surface for the antibiotic from the beginning would best be able to survive an attack by an antibiotic.
