ANS:B - ABS

The polymer obtained by copolymerization of three monomers is ABS (Acrylonitrile Butadiene Styrene). ABS is a terpolymer consisting of three monomers:

1. Acrylonitrile
2. Butadiene
3. Styrene

These monomers are polymerized together to form the ABS polymer, which exhibits a combination of properties derived from each monomer. ABS is known for its toughness, impact resistance, and heat resistance, making it a popular choice for a wide range of applications, including automotive parts, electronics housings, toys, and consumer goods.
