Nationalisation Defined as Government Takeover

Steps:

• Recall that nationalisation involves government intervention in the economy.
• Define it as shifting ownership of industries from private to public sector.
• Compare options to this definition: A relates to immigration, B to protectionism, C to planning, D to ownership transfer.
• Select D as it matches the core concept of control transfer.

Why D is correct:

• Nationalisation is the legal process where a government acquires private companies or assets for public control, as per economic policy definitions like those in the UK's 1940s coal and rail industries.

Why the others are wrong:

• A describes work visas or immigration policy, not ownership changes.
• B refers to tariffs or subsidies in protectionism, unrelated to takeover.
• C outlines central planning in command economies, not specifically ownership transfer.

Final answer: D
