Classification of plant mineral nutrients according to biochemical function

Mineral nutrient	Functions
A.)  Silicon(Si)	1.)    Constituent of alcohol dehydrogenase, glutamic dehydrogenase, carbonic anhydrase, etc
B.)  Manganese(Mn)	2.)    Component of sugar phosphates, nucleic acids, nucleotides, coenzymes, phospholipids, phytic acid, etc. Has a key role in reactions that involve ATP
C.)  Zinc(Zn)	3.)    Contributes to cell wall mechanical properties, including rigidity and elasticity.
D.)  Phosphorous(P)	4.)    Component of ascorbic acid oxidase, tyrosinase, monoamine oxidase, uricase, cytochrome oxidase, phenolase, laccase, and plastocyanin.
E.)   Copper(Cu)	5.)    Required for activity of some dehydrogenases, decarboxylases, kinases, oxidases, and peroxidases. Involved with other cation-activated enzymes and photosynthetic O2 evolution

Which of the following combination is correct?
