Explanation:

- Option 1: Full employment

- This is the classical view. They believe that free markets naturally adjust to ensure all available resources are used efficiently.

- The labor market clears, meaning everyone willing to work at current wages can find a job.

- This option aligns with classical economic theory.

- Option 2: Underemployment

- Underemployment means workers are employed at less than full capacity, which contradicts classical views.

- Classical economists believe in self-correcting markets, so they would dismiss this as a permanent state.

- Option 3: Over full employment

- This would suggest more jobs than workers, leading to unsustainable economic conditions.

- It's not a typical scenario addressed by classical economics.

- Option 4: None of these

- Classical economists emphasize natural, self-adjusting markets, typically dismissing sustained imbalances.
