Task: Class Definition Understanding (ontology: Food_Agriculture/Crop_Ontology)

Which of the following definitions best describes 'Calculation - Brown rice rate'?

A. Measure the distance from the base of the collar to the tip of the ligule on the penultimate leaf of five plants, and calculate the average
B. Collect 5-10 blooming florets of a male sterile line from different plants and measure the average angle of the opening between glumes (viz., lemma and palea)
C. Measure distance between the panicle neck node of the main culm and the panicle base, i.e. uppermost culm node. Repeat measurement on other representative plants and take the average.
D. Calculate as the ratio of brown rice weight (unprocessed rice with hulls removed) to rough rice weight (unprocessed rice with hulls intact) multiplied by 100

Answer: Calculate as the ratio of brown rice weight (unprocessed rice with hulls removed) to rough rice weight (unprocessed rice with hulls intact) multiplied by 100
