The correct option is A Silicone polymers
Silicone polymers is available in liquid, solid or gas phases as waxes or as rubbers.
In some cases, organic side groups can be used to link two or more of −Si−O− backbones together.
By varying the −Si−O− chain lengths, side chains crosslinking, silicones can be synthesized with a wide variety of properties and compositions.
They can vary in consistency from liquid to gel to rubber to hard plastic.
