Answer:
The correct answer would be option A.
Explanation:
Fungal infections are commonly very tough to treat because, not like bacteria cells, fungi are eukaryotes and more close to the animals. Many fungal diseases are superficial; that is, they occur on the animal's skin.
Antibiotics only attack and kill prokaryotes, whereas medications that kill or harm fungi cells also harm the eukaryotic animal host because both have a similar type of cell membrane.
Thus, the correct answer is option A.
