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

Which of the following definitions best describes 'Stover biomass yield at harvest (kg/ha) - Computation'?

A. Calculate by subtracting flag leaves weight from total leaves weight.
B. Calculate using the formula.
C. Lignin (ADL) concentration obtained from the Van Soest reference analyses, predicted using a Near Infra Red Spectroscopy (NIRS) calibration and calculated in reference to the Cell Wall Residue (CWR) content (estimated through the Neutral Detergent Fiber, NDF). The NIRS calibration information has to be provided. Method abbreviation: VSADLNDFNIRS
D. In Vitro Neutral Detergent Fiber Digestibility computation based on Near Infra Red Spectroscopy (NIRS) predictions. Information used to compute this trait correspond to the In Vitro Organic Matter Digestibility (IVOMD) estimated using Aufrere reference methods, the Mineral Matter content (MM) and the Neutral Detergent Fiber (NDF) content estimated using the Van Soest reference methods.

Answer: Calculate using the formula.
