Final answer:
Large carbon compounds formed from monomers are known as polymers. Proteins, starch, cellulose, DNA, and RNA are examples of biological polymers.
Step-by-step explanation:
Large carbon compounds consisting of monomers linked together are called polymers. Monomers are small, repeating units that bind together through covalent bonds to form these larger molecules. The process involved in linking these monomers to form polymers is known as polymerization. Plastics are a well-known type of synthetic polymer. In biology, there are several key polymers such as proteins, which are chains of amino acids, starch and cellulose, both of which are polymers of sugar molecules, and nucleic acids like DNA and RNA, which are polymers of nucleotides.
Therefore, the correct answer to your question is A) Polymers.
