Explanation:

- Production enterprises are typically categorized into economic sectors.

- Option 1: Two sectors

- This would split production into just two categories, such as primary and secondary, which is overly simplistic.

- Option 2: Three sectors

- The classic division of industries into:

1. Primary (agriculture, mining)

2. Secondary (manufacturing, construction)

3. Tertiary (services)

- This is the most widely accepted classification.

- Option 3: Four sectors

- Extends the three-sector model by adding the quaternary sector (information services) or quinary sector (executive and decision-making).

- Option 4: Five sectors

- Further division can occur by separately categorizing quaternary and quinary sectors.
