Brief Explanations:

• Drug abuse (A): It is a behavior that individuals can choose to change or stop, making it a controllable risk factor. For example, one can seek treatment and support to overcome drug abuse.
• Pollution (B): While efforts can be made to reduce pollution at a societal level, an individual has limited direct control over large - scale pollution. It often requires collective action and policy - making.
• Air (C): Air is a natural element. Although we can take some measures like using air purifiers in a limited space, we cannot fully control the overall quality and composition of air in the environment.
• Heredity (D): It is determined by our genetic makeup and cannot be changed. We inherit genetic traits from our parents, and there is no way to alter our hereditary factors.
