Answer: (B)

The biohazard symbol is universally recognized to indicate biological risk, which is why this choice is the correct answer. Its design is specifically intended to alert individuals to the presence of potentially harmful biological agents, such as infectious microorganisms, and it serves as a critical warning in a variety of settings, including laboratories, hospitals, and research facilities.

This recognition helps ensure that proper safety measures are taken around these hazards, regardless of the language spoken or the specific context, making it an essential component of health and safety protocols in situations where biological risks may be present. The symbol's prominence ensures that anyone seeing it understands that caution is necessary and that specific safety protocols should be followed to protect individuals from possible exposure to hazardous biological materials.
