Polyethylene
Polypropylene
Poly lactic acid
Polyester
Answer is Right!
Answer is Wrong!
The correct answer is C. Polylactic acid (PLA) is a biodegradable polymer. It is a type of polyester that is made from renewable resources such as corn starch or sugarcane. PLA is used in a variety of products, including food packaging, disposable cups and utensils, and 3D printing filament.
Polyethylene (A) and polypropylene (B) are both types of plastic that are not biodegradable. They are made from petroleum, a non-renewable resource. Polyester (D) is a type of plastic that can be biodegradable, but it is not as biodegradable as PLA.
PLA is a good choice for products that need to be disposed of in a sustainable way. It is also a good choice for products that come into contact with food, as it is non-toxic.
