Mineral nutrition deals with uptake and utilization of which type of nutrients by plants?
Go with B — Inorganic nutrients. Under MINERAL Transport, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Organic nutrients; C) Macromolecules; D) Secondary metabolites. When two options sound similar, choose the one that matches the textbook definition most tightly.
