Solution

The correct options are
A a- p
B b- p,q
D d-r,s
The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units.
Terylene is a condensation polymer. Monomers of Terylene is ethylene glycol and teri-phthalic acid.
Buna-S is formed by the monomeric addition of compound styrene (p) and butadiene (q).
Hence, options A, B and D are correct options.
