Matching pathogens to transmission methods: airborne, vector-borne, waterborne

Steps:

• Recall transmissions: Morbillivirus (measles) via airborne droplets; Mycobacterium (tuberculosis) via airborne droplets; Plasmodium (malaria) via mosquito vectors; Vibrio (cholera) via contaminated water.
• Identify table columns as airborne (1st), vector-borne (2nd), waterborne (3rd).
• Match pathogens: airborne fits Mycobacterium or Morbillivirus; vector fits Plasmodium; waterborne fits Vibrio.
• Select row with correct sequence: Mycobacterium (airborne), Plasmodium (vector), Vibrio (waterborne).

Why B is correct:

• Mycobacterium tuberculosis transmits via airborne respiratory droplets, Plasmodium via Anopheles mosquito bites, Vibrio cholerae via fecal-oral route in water.

Why the others are wrong:

• A: Second position (vector-borne) has Mycobacterium, which is airborne, not vector.
• C: Order mismatches columns—Plasmodium (vector) in airborne spot.
• D: Vibrio (waterborne) in airborne spot.

Final answer: B
