• A. A-II, B-I, C-IV, D-III
• B. A-III, B-IV, C-II, D-I
• C. A-III, B-II, C-IV, D-I
• D. A-IV, B-I, C-III, D-II

Hint:

Hybrid types:

- Double cross: (A × B) × (C × D).
- Heterosis: Mid-parent, better parent, standard.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of hybrid types and heterosis.

Step 2: Detailed Explanation:
Double cross hybrid (A): F1 (A × B) × F1 (C × D) (III).
F1 hybrid (B): Single cross hybrid (IV) (e.g., A × B).
Average heterosis (C): Mid-parent heterosis (II) (F1 over mid-parent).
Economic heterosis (D): Standard heterosis (I) (F1 over standard check).
Thus, the correct matching is A-III, B-IV, C-II, D-I.

Step 3: Final Answer:
Thus, the correct answer is A-III, B-IV, C-II, D-I, which corresponds to option (B).
