Question

Match the following diseases with their causative agents:

1. Common cold    A. Bacteria
2. Typhoid    B. Virus
3. Malaria    C. Protozoa

• A. \(1-B,\,2-A,\,3-C\)
• B. \(1-A,\,2-B,\,3-C\)
• C. \(1-C,\,2-A,\,3-B\)
• D. \(1-B,\,2-C,\,3-A\)

Hint:

Remember common disease-causing agents: Virus → Common cold, Dengue, AIDS. Bacteria → Typhoid, Cholera, Tuberculosis. Protozoa → Malaria, Amoebiasis.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The objective is to match specific human diseases listed in Column A with the correct category of pathogen that causes them in Column B.
Step 2: Detailed Explanation:
1. Common Cold: This is a viral infectious disease of the upper respiratory tract. It is primarily caused by Rhinoviruses. Thus, 1 matches with B (Virus).
2. Typhoid: This is an acute illness characterized by fever. It is caused by the bacterium Salmonella typhi. Thus, 2 matches with A (Bacteria).
3. Malaria: This is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. These parasites, specifically Plasmodium species, are Protozoa. Thus, 3 matches with C (Protozoa).
Step 3: Final Answer:
By matching the items: \(1 \rightarrow B\), \(2 \rightarrow A\), and \(3 \rightarrow C\).
This corresponds to option (A).
