Model Answer
Option (A): Both (A) and (R) are true and (R) is the correct explanation of (A).
The potato, introduced from the Americas, was nutritious and easy to grow on small plots, improving the diet and lifespan of Europe's poor.
Explanation
The NCERT textbook (Chapter 3 — The Making of a Global World) states that the potato improved the diet and longevity of the European poor. The reason correctly explains why — it was calorie-rich and grew well on small plots — making (R) a direct explanation of (A). So option (A) is correct.
