A.

"Scabies is a bacterial skin infection caused by Staphylococcus aureus."

B.

"Scabies is a parasitic skin infestation caused by the mite Sarcoptes scabiei."

C.

D.

"Scabies is a fungal infection caused by the fungus Candida albicans."

Answer and Explanation

The Correct Answer is B

Explanation: Scabies is a skin infestation caused by the Sarcoptes scabiei mite. The mite burrows into the skin, laying eggs and causing intense itching and a characteristic rash.

Incorrect choices: a. "Scabies is a bacterial skin infection caused by Staphylococcus aureus." - This statement is incorrect as scabies is caused by a parasitic mite, not a bacterial infection.

c. "Scabies is an autoimmune skin disorder that results in excessive skin shedding." - This statement is incorrect. Scabies is not an autoimmune disorder, and excessive skin shedding is not a characteristic feature of the condition.

d. "Scabies is a fungal infection caused by the fungus Candida albicans." - This statement is incorrect as scabies is caused by a mite, not a fungal infection.
