C) Correct. Crowded and poorly ventilated settings increase the risk of TB transmission, as the bacteria can be easily spread in close quarters.

A. "You should avoid close contact with family members until your TB treatment is completed." B. "Wear a mask at all times when at home to prevent the spread of TB." C. "Good hand hygiene and covering your mouth when coughing can help reduce the risk of transmission." D. "There is no need for any special precautions at home; TB is not easily transmitted."

Correct Answer is C

Explanation

A) Incorrect. While it is essential to minimize close contact, isolation from family members is not typically necessary. Effective treatment and infection control measures can reduce the risk of transmission.

B) Incorrect. Wearing a mask at all times at home may not be necessary, but it is important to follow respiratory hygiene practices, especially when close to others.
