A
Protozoa
B
Bacteria
C
Fungi
D
Viruses
Verified step by step guidance1
Understand the term 'virucidal': it refers to agents or disinfectants that specifically inactivate or destroy viruses.
Recall the classification of microorganisms: protozoa, bacteria, fungi, and viruses are distinct groups with different cellular structures and vulnerabilities.
Recognize that disinfectants are often categorized based on the type of microorganism they target, such as bactericidal (kill bacteria), fungicidal (kill fungi), and virucidal (kill viruses).
Since virucidals are designed to kill viruses, they are not effective against protozoa, bacteria, or fungi, which require different types of disinfectants.
Therefore, the correct association is that virucidals are disinfectants used to kill viruses.
