Fungal infections are often difficult to treat because fungi a. can use different modes of movement to move themselves away from any medicine that's harmful to them. b. can reproduce either sexually or asexually to avoid some types of medicine. c. can change their cell walls to develop antibiotic resistance. d. and animals are closely related and are both eukaryotic. many medicines that treat fungal infections are also harmful to animal cells.

The answer is D

Explanation: This is because fungus are Eukaryotic unlike bacteria.  

The correct answer will be option D.

Explanation:

Fungal infection are the infections caused by the fungi which are less common than infection caused by bacteria.

Fungi attack animals by direct colonizing and destroying the tissues and result in mycosis. Many fungal infections occur on the animal's skin.

Although rare, they are very difficult to treat as they are closely related to eukaryotic organisms and the compound that kill the fungi also harms the eukaryotic animal host. Additionally, antibiotics target only prokaryotic cells and not eukaryotic organisms. So, this limits the medical treatments that can be used against them.

thus, option D is the correct answer.
