Protectionism aims to shield domestic industries from foreign competition

Steps:

• Recall protectionism involves trade barriers like tariffs to favor local producers.
• Review aims: typically include boosting trade balance, safeguarding new industries, and curbing imports.
• Evaluate each option against these goals.
• Identify mismatch: option B focuses on exports, not imports.

Why B is correct:

• Protectionism targets restricting imports via higher costs, not raising export prices, which aligns with the definition of shielding domestic markets from foreign goods.

Why the others are wrong:

• A: Improves balance of trade by limiting imports to increase net exports.
• C: Protects infant industries by shielding them from established foreign competitors.
• D: Reduces import volume through barriers like quotas or tariffs.

Final answer: B
