A Correct answer
Explanation

Linear polymers consist of long and straight chains. The examples are high density polythene, polyvinyl chloride, etc. Branched chain polymers contain linear chains having some branches, e.g. low density polythene. Cross linked or Network polymers are usually formed from bi-functional and tri-functional monomers and contain strong covalent bonds between various linear polymer chains, e.g. bakelite, melamine, etc.
