Which statement about fungi is true?

• A. They cause superficial and systemic mycoses.
• B. They do not tolerate acidic conditions.
• C. They multiply only by binary fission.
• D. They require an intermediate host.

Answer: (A)

Fungi can cause infections that range from superficial conditions on the skin or nails to serious infections that spread inside the body, so saying they cause both superficial and systemic mycoses is true. They aren’t limited to a single way of growing in all circumstances; some reproduce by budding, some form spores, and others have hyphal fragmentation, so they multiply by more than binary fission. They also do not require an intermediate host to complete their life cycles; most fungal infections come from environmental exposure to spores or fungi, not from passing through another host. The idea that they cannot tolerate acidic conditions or that they must rely on an intermediate host doesn’t fit how fungi typically behave.
