Primary succession is most likely to occur in situations where an ecosystem is starting from bare rock or a lifeless environment, without soil. Among the options provided, the situation that best fits this description is:
**Sheets of ice that once covered an area melt away, exposing a layer of rock.**
This scenario represents a new habitat that lacks soil and established plant life, making it a classic example of primary succession. In contrast, the other options involve disturbances to existing ecosystems where soil and some form of life are already present, which would typically lead to secondary succession.
