Which of the following polymer type is not classified on the basis of its application.a.rubbersb.fibersc.plasticsd.synthetic

The question is asking which type of polymer is not classified based on its application. The options are:

a. Rubbers b. Fibers c. Plastics d. Synthetic

To answer this question, we need to understand what each term means:

a. Rubbers: These are elastic materials that are used in a variety of applications, including tires, gloves, and insulation.

b. Fibers: These are long, thin strands of material that are used in textiles, rope, and other applications.

c. Plastics: These are materials that can be molded into a variety of shapes and are used in a wide range of applications, from packaging to furniture.

d. Synthetic: This term refers to materials that are not naturally occurring but are instead created through chemical processes.

Based on these definitions, the answer is d. Synthetic. This is because "synthetic" is a term that describes how a material is made, not how it is used. The other three options (rubbers, fibers, and plastics) all describe types of materials that are classified based on their application.
