Answer 1

The correct option is A (A) $\to$ (ii), (B) $\to$ (iii), (C) $\to$ (iv), (D) $\to$ (i)

PVC	(ii)Thermoplastic
Condensation polymer	(iii)Dacron
Polysaccharide	(iv)Natural polymer
Elastomer	(i) Rubber

[A] PVC- It is most commonly used thermoplastic, it is naturally white and very brittle,

[B] Condensation polymerisation- This type of polymerisation generally involves a repetitive condensation reaction between two bi-functional monomers and lead to the formation of high molecular mass condensation polymers.

[C] Polysaccharide-Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages,

[D] Elastomer- These are rubber-like solids with elastic properties.

The correct option is [A].
