Answer: (D)

If both assertion and reason are false.

Answer 2

All enzymes are made up of proteins and all proteins do not have 3-dimensional structures as proteins are classified into primary, secondary, tertiary and quaternary structures and only tertiary has 3-dimensional structure. The sequence in which the amino acids are arranged in a protein is called primary structure of protein.
