The Correct Option is C

Solution and Explanation


Step 1: Concept
After milling, the rice consists of a mixture of full grains (head rice) and fragments (broken rice).

Step 2: Meaning
Separation is required to categorize the rice based on grain length to meet commercial standards.

Step 3: Analysis
A grader, often in the form of a shifted screen or an indented cylinder grader, uses physical dimensions to sort the grains. It allows the shorter, broken pieces to be removed from the longer, whole grains.

Step 4: Conclusion
Therefore, a grader is the specific machine used for this classification.
