Protectionism opposes globalization by restricting trade

Steps:

• Define globalization as the increasing interconnectedness of economies through trade, investment, and markets.
• Identify factors that promote it, like open markets and investments, versus those that hinder it, like barriers to trade.
• Review choices: A, B, and C facilitate global links, while D imposes restrictions.
• Select D as it directly counters economic integration.

Why D is correct:

• Protectionist policies, by definition, use tariffs, quotas, or subsidies to shield domestic industries from foreign competition, reducing cross-border trade and investment flows.

Why the others are wrong:

• A: A single world market eliminates barriers, boosting global trade.
• B: Direct foreign investment expands multinational operations across borders.
• C: Trade in financial services increases international capital mobility.

Final answer: D
