• C. Cleaning
• D. Pearling

Hint:

Sorting = Separation by a single physical property (e.g., size).
Grading = Separation by commercial quality/value.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Post-harvest handling distinguishes between cleaning, sorting, and grading based on operational objectives and value assessment criteria.

Step 2: Detailed Explanation:
1. Grading: The systematic classification of commercial agricultural commodities into distinct quality categories and price brackets according to standardized commercial specifications (size, shape, color, maturity, defect-free quality).
2. Sorting: Separation based on a single physical property (e.g., size, shape, or density) into uniform lots.
3. Cleaning: Removal of foreign contaminants, dust, chaff, weed seeds, and inert matter.
4. Pearling: Debranning and polishing cereal grain surfaces.

Step 3: Final Answer:
Therefore, separating material according to commercial value is Grading, corresponding to option (B).
