Identify the type of polymer.
(i) - A - A - A - A - A - A-
(ii) - A - B - B - A - A - A - B - A -

Explanation:

• Homopolymer - If only one type of monomeric unit takes part to form a polymeric structure, it is called as a homopolymer.
• Example = Glycogen, starch, chitin

Since (i) is made up of only A type of monomer, it is a homopolymer

• Copolymer - If two types of monomeric units take part to form a polymeric structure, it is called as a copolymer.
• Example = Nylon6-6, dacron, glyptal

Since (ii) is made up of A and B type of monomer, it is a copolymer.

Hence, option (A) is correct.
