The correct answer is: Elastomer < Plastic < Fibre
Elastomers or rubbers have the weakest intermolecular forces of attraction followed by plastics while fibres have the strongest forces of attraction. Thus, the increasing intermolecular forces of attraction follows the order

elastomer < plastic < fibre.
