**Core Concept**
An ideal disinfectant is a chemical agent that effectively kills or inactivates microorganisms on a surface, without causing harm to humans, animals, or the environment. The properties of an ideal disinfectant include broad-spectrum activity, stability, and efficacy against a wide range of microorganisms, including bacteria, viruses, and fungi.

**Why the Correct Answer is Right**
The correct answer will be a property that is not characteristic of an ideal disinfectant. This could be related to the toxicity of the disinfectant, its environmental impact, or its inability to effectively kill certain types of microorganisms.
