Task: Class Definition Understanding (ontology: Earth_Environment/EnvironmentOntology)

Which of the following definitions best describes 'macronutrient'?

A. Any nutrient required in large quantities by organisms throughout their life in order to orchestrate a range of physiological functions. the concept are usually chemical elements (carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur) that humans consume in the largest quantities. Calcium, sodium, magnesium and potassium are sometimes included as the concept because they are required in relatively large quantities compared with other vitamins and minerals.
B. A macronutrient role which inheres in nitrate, nitrogen dioxide, ammonium, silicon, or phosphate dissolved in ocean water.
C. A container which is typically made of glass or plastic and having a tapered neck, used primarily for holding liquids.
D. Fluid environmental material which is present in the continental crust and dictates the nature and extent of crustal deformation.
