Question

Match the LIST-I with List-II 

LIST-I	LIST-II
A. BCG	III. Live attenuated
B. Rabies	II. Killed whole organism
C. Tetanus	I. Toxoid
D. Pneumococcus	IV. Polysaccharide

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

Hint:

Vaccines are classified based on the nature of the agent used to provoke an immune response.

Answer 1

The Correct Option is A

To solve the matching problem, we will correctly associate each item from LIST-I with the appropriate type of vaccine from LIST-II:

• BCG is a vaccine used against tuberculosis and is a live attenuated vaccine, which is where live virus or bacteria are weakened. Thus, it matches with III. Live attenuated.
• The Rabies vaccine uses inactivated viruses, making it a killed whole organism vaccine. Therefore, it matches with II. Killed whole organism.
• The Tetanus vaccine is a toxoid, which means it contains a toxin that has been rendered harmless but still elicits an immune response. This matches with I. Toxoid.
• The Pneumococcus vaccine typically includes polysaccharide surfaces from the bacterium. Hence, it corresponds to IV. Polysaccharide.

Based on these comparisons, the correct matching will be:

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