The correct Answer is:
### Step-by-Step Solution 1. **Identify the Diseases**: The question presents four diseases: Hepatitis, AIDS, Common Cold, and Malaria. 2. **Understand Modes of Transmission**: - **Hepatitis**: Primarily transmitted through sexual contact, blood transfusions, and body secretions (sweat, saliva, urine). - **AIDS**: Transmitted through sexual contact, blood transfusions, and from mother to child. - **Common Cold**: Transmitted through respiratory droplets (coughing and sneezing), contact with contaminated surfaces, and close personal interactions. - **Malaria**: Transmitted exclusively by mosquito bites; it cannot be spread through casual contact. 3. **Compare Infectiousness**: - Hepatitis and AIDS have limited modes of transmission compared to the Common Cold. - The Common Cold can be spread through the air and by contact with contaminated surfaces, making it highly contagious. - Malaria is not spread through casual contact, limiting its infectiousness. 4. **Conclusion**: Based on the modes of transmission, the Common Cold is the most infectious disease among the options provided because it can spread easily through the air and contact with contaminated surfaces. ### Final Answer The most infectious disease among the options is the **Common Cold**.
