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

Which of the following definitions best describes 'Stem Biomass moisture content - Computation'?

A. Cellulose 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: VSCellNDFNIRS.
B. Cellulose concentration obtained from the Van Soest reference analyses, predicted using a Near Infra Red Spectroscopy (NIRS) calibration and calculated in reference to the Dry Matter (DM) content. The NIRS calibration information has to be provided. Method abbreviation: VSCellDMNIRS
C. Calculate by subtracting flag leaves weight from total leaves weight.
