Question

which of the following is true of pathogenic fungi?
○ infections occurs accidental contact
○ primary pathogens sicken healthy people
○ opportunistic pathogens attack people with weakened immune systems.
○ all of the above

Explanation:

• Analyze each option:
• "Infections occurs accidental contact": Pathogenic fungi infections can occur via accidental contact (e.g., contact with contaminated surfaces/objects).
• "Primary pathogens sicken healthy people": Primary fungal pathogens can infect immunocompetent (healthy) individuals (e.g., Histoplasma capsulatum).
• "opportunistic pathogens attack people with weakened immune systems": Opportunistic fungi (e.g., Candida, Aspergillus) target hosts with compromised immunity (e.g., AIDS patients, transplant recipients).
• Since all three statements are correct, the answer is "All of the above".

Answer:

D. All of the above
