Correct Answer: A

Rationale: Healthcare workers are at a higher risk of contracting Hepatitis B due to the nature of their work, which involves frequent exposure to blood and bodily fluids. Needle-stick injuries, which occur when a healthcare worker accidentally punctures their skin with a contaminated needle, are a common mode of transmission for Hepatitis B. This is why it is crucial for healthcare workers to follow strict safety protocols, such as using needle safety devices and practicing proper infection control measures, to minimize the risk of contracting Hepatitis B and other bloodborne diseases.
