Correct Answer is A
Explanation

B) Incorrect. LTBI is not contagious, whereas active TB disease is contagious.
C) Incorrect. LTBI and active TB disease have different symptoms and treatment approaches. LTBI has no symptoms, while active TB disease presents with symptoms and requires treatment to prevent progression.

Correct Answer is A
Explanation

C) Incorrect. Latent TB infection can occur in various parts of the body, not just the lungs, and it typically does not cause symptoms.
