Best answer

Answer: 3. Lipids

Key idea: A polymer is a long chain of repeating monomer units.

Proteins: chains of amino acids.
Polysaccharides: chains of monosaccharides.
Nucleic acids: chains of nucleotides.
Lipids (fats, oils) are built from glycerol and fatty acids and are not long chains of a repeating unit, so they are not polymeric.

Answer: (3).
