Answer

**Step-by-Step Solution:**

1. **Definition of Communicable Disease**: A communicable disease is an illness that can be transmitted from one person to another. This transmission can occur through direct contact, droplets in the air, or other means.

2. **Transmission of Common Cold**: The common cold is caused by a group of viruses known as rhinoviruses. When a person who is infected with the common cold sneezes or coughs, they release tiny droplets into the air that contain the virus.

3. **Infection of Healthy Individuals**: When a healthy person inhales these droplets, the rhinoviruses enter their body, leading to infection. This process of spreading the disease from an infected person to a healthy person is what makes the common cold a communicable disease.

4. **Symptoms of Common Cold**: The common cold typically manifests with symptoms such as nasal discharge, sore throat, cough, and headache. These symptoms usually last for about 3 to 7 days.

5. **Conclusion**: Since the common cold can be easily spread from one person to another through respiratory droplets, it is classified as a communicable disease.
