Detailed explanation-1: -The macromolecule that requires the element sulfur (S) is c) proteins. Proteins are made of amino acids, small molecules with a carboxyl group, amino group, and a variable R-group. In some amino acids such as methionine and cysteine, sulfur forms part of the R-group.

Detailed explanation-2: -Methionine and cysteine are the two primary sulfur-containing amino acids in mammals. Methionine is an essential amino acid, obtained by dietary intake while cysteine is non-essential and a metabolite of methionine metabolism.

Detailed explanation-3: -All macromolecules also contain the elements hydrogen and oxygen. Some macromolecules contain the elements nitrogen, phosphorus, and sulfur. Together, these are the six elements most commonly found in living organisms.

Detailed explanation-4: -In fact, sulfur occurs in all the major classes of biomolecules, including proteins, sugars, nucleic acids, vitamin cofactors and metabolites, and is required by all living organisms.

Detailed explanation-5: -Proteins contain between 3 and 6% of sulfur amino acids. A very small percentage of sulfur comes in the form of inorganic sulfates and other forms of organic sulfur present in foods such as garlic, onion, broccoli, etc.
