Solution

The correct option is B Nylon 6,6
Condensation polymers are formed by the repeated condensation reaction between two different bi-functional or tr-functional monomeric units, along with the loss of small molecules like water, alcohol, HCl, etc. Nylon-6,6 is formed by the condensation of hexamethylene diamine and adipic acid, resulting in loss of water molecules.
