Disaster risk definition – UGC NET Question

Disaster risk arises when a potentially damaging physical event interacts with vulnerable people, infrastructure and ecosystems. A strong hazard in an uninhabited area may not create a disaster, whereas a moderate hazard in a very vulnerable community can be devastating. Therefore, risk is commonly conceptualised as a function or product of hazard and vulnerability, with exposure explicitly considered in many formulations.

Option A:
Option A is incorrect because hazard alone does not determine risk; context and vulnerability matter greatly.

Option B:
Option B is incorrect since vulnerability without a triggering hazard does not lead to a disaster.

Option C:
Option C is correct as it captures the widely used risk equation linking hazard, vulnerability and exposure.

Option D:
Option D is incorrect; early warning and participation reduce risk, but they are not the definition of risk itself.
