Explanation:

Question 9

Tuberculosis (TB) diagnosis: A positive skin test (Mantoux test) detects TB infection. Chest X - rays show lung abnormalities from TB. Acid - fast staining identifies Mycobacterium tuberculosis. So all these methods are used, making "all of the above" correct.

Mycobacterium tuberculosis in fine aerosols (droplet nuclei) can survive for hours to days, not 10 years. So the statement is false.

GALT (gut - associated lymphoid tissue) includes tonsils/adenoids, Peyer's patches, and appendix. The gallbladder is for bile storage, not part of GALT. So gallbladder is the exception.

Answer:

D. all of the above (assuming options are labeled A - D as positive skin test, chest X rays, acid - fast staining, all of the above)
