Incomplete Data Prevents Analysis Steps:

• Identify production capacities: Country Y produces 500 mobile phones or 400 televisions with all resources.
• Note missing data: No production figures provided for Country X.
• Recall definitions: Absolute advantage requires higher output in at least one good; comparative advantage requires lower opportunity cost.
• Conclude: Cannot compare advantages without Country X's data.

Why B is correct:

• Not enough information to verify, as Country X's production is absent.

Why the others are wrong:

• A: Lacks Country X data to confirm advantages.
• C: Insufficient details for Country Y's advantages.
• D: No basis to assess without full table.

Final answer: Not enough information.
