Which term refers to substances that kill fungi?

• A. Fungicidals
• B. Viricidals
• C. Tuberculoidals
• D. Disinfectants

Answer: (A)

The key idea here is identifying a word that means killing fungi. The suffix “-cidal” means killing, and when paired with “fungi” it pinpoints the target as fungi. So fungicidal substances are specifically designed to destroy fungal organisms, which is why this term is the correct label in this context.

Viricidals would target viruses, not fungi, so they don’t fit. Tuberculoidals isn’t a standard or correct term used to describe antifungal action. Disinfectants are broad agents that kill a wide range of pathogens on surfaces, including some fungi, but they aren’t described by a specific fungi-killing label the way fungicidal is, so fungicidal is the precise answer.
