Explanation

To determine which of the following diseases is non-communicable, we will analyze each option provided:

1. **Diphtheria**:
- Diphtheria is caused by a bacterium known as *Corynebacterium diphtheriae*. This disease is spread from person to person through respiratory droplets or contact with contaminated surfaces. Therefore, it is a communicable disease.

2. **Flu (Influenza)**:
- The flu is caused by the influenza virus. It is also transmitted through respiratory droplets when an infected person coughs or sneezes. Thus, the flu is a communicable disease.

3. **Cancer**:
- Cancer is not caused by infectious agents and cannot be transmitted from one person to another. It occurs due to uncontrolled cell division, often influenced by genetic factors and environmental exposures. Therefore, cancer is classified as a non-communicable disease.

4. **Malaria**:
- Malaria is caused by the protozoan parasite *Plasmodium vivax*, which is transmitted through the bite of infected mosquitoes. This makes malaria a communicable disease.

After analyzing all the options, the only non-communicable disease among them is **cancer**.

**Final Answer**: The correct answer is option **c) cancer**.
