Hint: The polymer is large molecules which are also called macromolecules. They are made from the addition or condensation of small monomers which may be monofunctional or bifunctional. Monofunctional monomers give us additional polymers while bifunctional monomers give us condensation polymers.
Complete Step by Step Solution:
Terylene is a form of condensation polymer arised from the condensation of ethylene glycol and terephthalic acid. The condensation has an outcome in the form of loss of water molecules. The condensation is written as:

Terylene is synthesised by the condensation of an alcohol i.e. ethylene glycol and an acid i.e. terephthalic acid. The reaction between alcohol and acid results in the development of an ester bond. As the monomers of ethylene glycol and terephthalic acid are associated by ester linkages and the ester is used for preparing clothes. So we call terylene a polyester fibre.
Terylene is a fibre , and not a thermosetting plastic because when we heat them they melt and do not show plastic property.
Terylene is made by the condensation of repeating units of bifunctional monomers to form long-chain polymers. In this whole process, the monomers merged to form dimmers then trimers then oligomers, and finally polymers. So terylene is a step-growth polymer.
Thus, Option (D) is correct.
Note: Terylene is not a chain growth polymer as they synthesised from the linkage of monomers with double and triple bonds. They are also called addition polymers. As it is synthesised by the condensation of two monomer units, so terylene is not a chain growth polymer.
