  3. Dacron

  4. PVC

A,D Correct answer
Explanation
The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units. 

In these polymerisation reactions, the elimination of small molecules such as water, alcohol, hydrogen chloride, etc. take place. The examples are terylene (dacron), nylon 6, 6, etc. For example, nylon 6, 6 is formed by the condensation of hexamethylenediamine with adipic acid.

When two different types of monomers are joined in the same polymer chain, the polymer is called a copolymer. 
Nylon 6 is a condensation polymer but it's not a co-polymer.
PVC is an addition polymer.

Hence, options A and D are correct.
