Step 1: Classify farm holdings in India based on size.
- Marginal: Less than 1 hectare.
- Small: 1–2 hectares.
- Semi Medium: 2–4 hectares.
- Medium: 4–10 hectares.
- Large: Greater than 10 hectares.
Step 2: Arrange classifications in ascending order of size.
Marginal<Semi Medium<Medium<Large.
Step 3: Assign letters to each classification based on size.
- B represents the smallest (Marginal).
- C represents the next smallest (Semi Medium).
- D represents a larger size (Medium).
- A represents the largest (Large).
Step 4: Determine the correct sequence of letters.
The correct order, from smallest to largest farm holding, is B, C, D, A.
