Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R . Assertion A : Dacron is an example of polyester polymer. Reason R : Dacron is made up of ethylene glycol and terephthalic acid monomers. In the light of the above statements, choose the most appropriate answer from the options given below.

Options

  1. ABoth A and R are correct and R is the correct explanation of A
  2. BBoth A and R are correct but R is NOT the correct explanation of A .
  3. CA is correct but R is not correct.
  4. DA is not correct but R is correct.

Correct answer

A. Both A and R are correct and R is the correct explanation of A

Step-by-step solution

The formation of terylene or Dacron by the interaction of ethylene glycol and terephthalic acid is an example of this type of polymerisation.
