First, let's restate the question and the available choices to set the stage for evaluation.
Question: Specialization and international trade will
Options:
- A) make a nation consume a combination on its production possibilities frontier.
- B) move a nation to a point inside its production possibilities frontier.
- C) result in a rightward shift of a nation's production possibilities frontier.
- D) allow a nation to consume beyond its production possibilities frontier.

Option A: 'make a nation consume a combination on its production possibilities frontier.' This statement is incorrect because specialization and trade typically allow a country to consume beyond its own PPF by exploiting comparative advantage and trading with others, rather than forcing consumption to lie exactly on its own frontier.

Option B: 'move a nation to a point inside its production possibilities frontier.' The idea of moving inward is inconsistent with the effects of specialization and trade, which generally expand achievable consumption beyond the domestic PPF due to gains from trade; inward movement would imply a worse or constrained outcome, not the usual effect of trade.

Option C: 'result in a rightward shift of a nation's production possibilities frontier.' The PPF itself is determined by resources and technology; specialization and trade do not inherently increase that frontier—trade expands consumption possibilities, but it does not directly enlarge the maximum production capabilities, so this option misstates the nature of the change.

Option D: 'allow a nation to consume beyond its production possibilities frontier.' This captures the core insight of trade: by specializing according to comparative advantage and trading, a country can reach a higher, combined level of consumption than it could achieve by producing everything domestically, effectively consuming beyond its own PPF.

In evaluating these options, consider how trade changes feasible consumption sets rather than production capabilities: gains from trade arise because relative efficiency differences let each country specialize and then exchange, leading to a higher community of consumption possibilities than any one country could produce alone.

Taken together, the most accurate statement aligns with the standard point that specialization and international trade enable consumption beyond the nation’s own production possibilities frontier, rather than simply moving along, inside, or shifting the frontier itself. The other options describe outcomes that do not reflect the typical mechanism and consequences of trade and specialization, or contradict the idea of gains from trade.
