A country is allowed to import just 50,000 tonnes of rice annually. This describes

Step 1: Analyze the question The question describes a limit on the quantity of rice a country may import in a year (50,000 tonnes). We need the trade term for this.

Step 2: Explain the concepts

• Devaluation: A deliberate lowering of the value of a country's currency relative to other currencies. It has nothing to do with limiting import quantities.
• Tariff: A tax or duty placed on imported goods. It limits imports by raising their price, not by setting a fixed quantity.
• Embargo: A complete ban on trade with a particular country, or on a particular good. It allows no imports at all, so it is not a limit of 50,000 tonnes.
• Quota: A physical limit on the quantity or value of a good that may be imported (or exported) in a given period.

Step 3: Apply to the question Allowing "just 50,000 tonnes annually" is a fixed quantity limit over a set period. That is exactly what a quota is.

Step 4: Answer The correct option is D. quota.

Tip: Link each term to a keyword:

• Quota = Quantity
• Tariff = Tax
• Embargo = Entirely banned
• Devaluation = Drop in currency value

When you see a specific amount allowed, think quota.
