Assertion: Communicable diseases are also called infectious diseases.
Reason: Cancer is a communicable disease.
Explanation:
The correct answer is option C: Assertion (A) is true but reason (R) is false.
Let's analyze the statements given in the question:
1. Assertion (A): Communicable diseases are also called infectious diseases.
This statement is true. Communicable diseases are those diseases that can be transmitted from one person to another, either directly or indirectly. These diseases are caused by infectious agents such as bacteria, viruses, fungi, or parasites. Examples of communicable diseases include common cold, influenza, tuberculosis, and measles.
2. Reason (R): Cancer is a communicable disease.
This statement is false. Cancer is not a communicable disease. Unlike communicable diseases, cancer is not caused by infectious agents. Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. It is caused by genetic mutations or exposure to certain risk factors such as tobacco smoke, radiation, or certain chemicals. Cancer cannot be transmitted from one person to another through direct or indirect contact.
Therefore, while the assertion is true that communicable diseases are also called infectious diseases, the reason given is incorrect as cancer is not a communicable disease.
