Answer 1

Answer: (B)

Which help in metabolic functions.

Minor elements are those elements which are required in small quantity. This is because most of these elements are required as coenzymes for enzymes which carry out metabolic reactions. Major elements are those elements which are required by plants in larger quantity because they have a structural role and are components of structural macromolecules.
