Question

Arrange these ICAR Institutes in order of their location from South to North in India.
(A) Central Agro-forestry Research Institute
(B) National Bureau of Plant Genetics Resources
(C) Indian Institute of Maize research
(D) Central Tuber Crops Research Institute
Choose the correct answer from the options given below:

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

Hint:

To solve latitudinal sorting questions quickly:
Always pinpoint the extremes. Kerala (CTCRI) is near the equator, making (D) the starting point. Punjab (IIMR) is the furthest north, making (C) the ending point.
This immediately reveals the sequence starts with (D) and ends with (C), pointing directly to Option 4.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The Indian Council of Agricultural Research (ICAR) has established specialized research institutes across India.
This question requires geographical knowledge of their headquarters and their relative latitudinal positions from South to North.

Step 2: Detailed Explanation:
Let us identify the headquarters of each ICAR institute and determine their latitudes:
- (D) Central Tuber Crops Research Institute (CTCRI): Located in Thiruvananthapuram, Kerala.
Its latitude is approximately \(8.5^\circ\text{ N}\). This is the southernmost institute in the list.
- (A) Central Agro-forestry Research Institute (CAFRI): Located in Jhansi, Uttar Pradesh.
Its latitude is approximately \(25.4^\circ\text{ N}\). This lies in central-north India.
- (B) National Bureau of Plant Genetic Resources (NBPGR): Located in New Delhi.
Its latitude is approximately \(28.6^\circ\text{ N}\). This lies in northern India, north of Jhansi.
- (C) Indian Institute of Maize Research (IIMR): Historically located in New Delhi, its headquarters was shifted to Ludhiana, Punjab in 2015.
Ludhiana is located at approximately \(30.9^\circ\text{ N}\). This is the northernmost institute in the list.
Arranging these latitudes in ascending order (from South to North):
\[ 8.5^\circ\text{ N (D)} \rightarrow 25.4^\circ\text{ N (A)} \rightarrow 28.6^\circ\text{ N (B)} \rightarrow 30.9^\circ\text{ N (C)} \]
Thus, the correct sequence is (D), (A), (B), (C).

Step 3: Final Answer:
The correct option is (D).
