Final answer:
Optimists(option C) are the ones who believe that human innovation will avert potential disasters, aligning with the Cornucopian Theory.
Step-by-step explanation:
The belief that human innovation will avert potential disasters is most closely associated with optimists. Optimists tend to believe in the positive outcomes of situations and often subscribe to the Cornucopian Theory, which posits that human ingenuity can resolve any environmental or social issues that develop, including those brought on by population growth or resource scarcity.
On the contrary, pessimists might focus on the potential ecological collapse and difficulties associated with human activities, while realists may look at both the potential disasters and factual data before making a judgment. Fatalists, meanwhile, would believe that events are predetermined and thus unlikely to change regardless of human innovation.
Therefore, the idea that human innovation will avert potential disasters is optimistic and the correct answer is C) Optimists.
