Step 1: Understanding the Concept:
Agronomy and crop science use specific morphological, physiological, and commercial terms to describe the growth, reproductive structures, and varieties of major crops.
Detailed Explanation:
Let us correlate each crop from List I with the corresponding term in List II:
- A. Wheat: The inflorescence of a wheat plant is botanically termed a V. Spike.
- B. Chickpea: Chickpea varieties are commercially classified into two main types: Desi (small, dark-seeded) and IV. Kabuli type (large, cream-colored seeds).
- C. Groundnut: After fertilization in groundnut, the pedicel elongates to form a "peg" that grows downwards into the soil to develop pods. This growth directed toward the earth is a classic example of positive II. Geotropism.
- D. Sugarcane: The emergence of the tassel or inflorescence in sugarcane is called arrowing, and the inflorescence itself is known as the III. Arrow.
- E. Rapeseed-mustard: The characteristic fruit type of the Brassicaceae family, which includes mustard, is called a I. Siliquae (or siliqua).
Mapping these associations, we obtain: A - V, B - IV, C - II, D - III, E - I.
Step 2: Final Answer:
This matches Option (D).
