B Correct answer
Explanation

Immune dysfunctioning is an internal factor within the body's systems, not an external environmental factor. External factors affecting health include environmental pollution, alcohol consumption (lifestyle choice), and global warming (environmental change) - all originate outside the body. Immune dysfunction is internal to the body's defense system.
