Concept:
Disaster risk is generally understood as a function of the hazard, the exposed elements and their vulnerability. The question asks which statement is incorrect.
Step 1:
The level of risk genuinely depends on the nature of the hazard, on the vulnerability of the exposed community, and on the economic value of the assets at risk. These three are valid factors.
Step 2:
Risk is defined in terms of hazard, exposure and vulnerability rather than directly on human activities. While human activities may influence hazard or vulnerability indirectly, the statement that risk depends on human activities is the odd one out and is treated as incorrect here.
Answer: Option (4) — The level of risk will depend on the human activities.
