‘Disinfectant’ kills the following –
**Core Concept**
Disinfectants are chemical agents used to inactivate or destroy microorganisms on non-living surfaces and objects, thereby preventing the spread of infections. Disinfectants target a wide range of pathogens, including bacteria, viruses, and fungi, but their primary goal is to eliminate microbial life forms.
**Why the Correct Answer is Right**
The correct answer is likely to be all pathogens mentioned in the options, as disinfectants are designed to be broad-spectrum antimicrobial agents. Disinfectants work by denaturing proteins, disrupting cell membranes, or interfering with essential metabolic processes in microorganisms. Examples of disinfectants include bleach, quaternary ammonium compounds, and hydrogen peroxide. These agents are commonly used in healthcare settings to decontaminate surfaces, equipment, and medical instruments.

**Option C:** This option is not specified, so we cannot provide an explanation for it.
**Clinical Pearl / High-Yield Fact**
It's essential to note that disinfectants are not the same as antiseptics. Antiseptics are used to prevent infection on living tissues, whereas disinfectants are used to eliminate microorganisms on non-living surfaces and objects.
