Which of the following is an example of a biohazardous condition?

A biohazardous condition refers to any threat that poses a risk to human health or the environment due to biological agents. In this case, an infection from bloodborne pathogens is a prime example of a biohazardous condition. Bloodborne pathogens are microorganisms found in human blood that can lead to diseases, such as HIV and hepatitis B and C. These pathogens can be transmitted through direct contact with contaminated blood or body fluids, thus creating significant health risks, especially in medical or laboratory settings.

In contrast, a clean water supply, exposure to sunlight, and household waste disposal do not inherently involve biological materials that can threaten health in the same way. A clean water supply promotes health and safety, while exposure to sunlight can contribute to vitamin D production, and household waste disposal is typically managed under regulated waste management processes that minimize health risks. Therefore, the correct option aptly highlights a condition that can lead to serious health implications due to the presence of harmful biological agents.
