• B. A-II, B-III, C-I, D-IV
• C. A-IV, B-III, C-II, D-I
• D. A-I, B-II, C-III, D-IV

Hint:

Malaria spreads by Anopheles mosquito, while Dengue spreads by Aedes mosquito.

Answer 1

The Correct Option is B

Concept: Different infectious diseases are caused or transmitted by specific organisms or vectors.
• Malaria is transmitted by female Anopheles mosquito.
• Dengue is transmitted by Aedes mosquito.
• Tuberculosis is caused by Mycobacterium tuberculosis.
• AIDS commonly spreads through unprotected sexual intercourse.

Step 1: Match Malaria.
Malaria is transmitted through the bite of infected female Anopheles mosquito. Hence, \[ A \rightarrow II \]

Step 2: Match Dengue.
Dengue fever is spread by Aedes mosquito. Hence, \[ B \rightarrow III \]

Step 3: Match Tuberculosis.
Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. Hence, \[ C \rightarrow I \]

Step 4: Match Acquired Immuno-Deficiency Syndrome.
AIDS can spread through unprotected sexual intercourse and other body fluid exposures. Hence, \[ D \rightarrow IV \]

Step 5: Select the correct option.
Thus, the correct matching is: \[ A-II,\; B-III,\; C-I,\; D-IV \] Therefore, the correct answer is: \[ \boxed{(B)\ A-II,\; B-III,\; C-I,\; D-IV} \]
