Question

Arrange the countries based on their contribution to world wheat production (highest to lowest).
(A) India
(B) United States of America
(C) Russian Federation
(D) China

• A. (A), (D), (C), (B).
• B. (A), (C), (B), (D).
• C. (B), (A), (D), (C).
• D. (D), (A), (C), (B).

Hint:

While China and India are the top two producers of wheat, most of their production is consumed domestically. Russia is actually the world's largest exporter of wheat.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Wheat (*Triticum aestivum*) is a staple cereal crop grown globally.
Understanding global agricultural production statistics helps identify the key nations driving world food security and grain exports.

Step 2: Detailed Explanation:
Let us review the global wheat production rankings based on data from the Food and Agriculture Organization (FAO):
1. China (D): China is the world's largest producer of wheat, consistently producing over $135 \text{ million metric tonnes}$ annually due to intensive agricultural practices and large cultivated areas.
2. India (A): India is the second largest producer of wheat, with annual production averaging around $105-110 \text{ million metric tonnes}$, primarily grown in the northern and northwestern plains.
3. Russian Federation (C): Russia is the third largest producer and the world's leading exporter of wheat, producing around $75-85 \text{ million metric tonnes}$ annually.
4. United States of America (B): The USA is another major wheat producer and exporter, typically ranking fourth or fifth with an annual production of around $45-50 \text{ million metric tonnes}$.
Therefore, arranging these countries from highest to lowest production yields the sequence: (D) China $\rightarrow$ (A) India $\rightarrow$ (C) Russian Federation $\rightarrow$ (B) United States of America.

Step 3: Final Answer:
The correct descending sequence is (D), (A), (C), (B), corresponding to option (D).
