Explanation:

- A rise in GNP (Gross National Product) indicates economic growth and increased national income.

- Option 1: Exports

- Increased GNP often means production capabilities have improved.

- Higher productivity can lead to more goods available for export.

- Option 2: Imports

- A richer economy can afford more imports.

- Consumers and businesses might import more goods for consumption and production.

- Option 3: Both

- Both exports and imports might rise with increased GNP.

- Boosted productivity can lead to export growth while higher income means higher import capacity.

- Option 4: None of these

- Highly unlikely, as economic growth typically impacts both exports and imports.

Option 3: Both is the correct answer.
