Fibreglass is made from extremely fine fibres of what?

Explanation:
Fibreglass is a composite where the reinforcing fibres are glass. These fibres are drawn from molten glass into very thin strands and then embedded in a polymer resin to form the material. The glass fibres provide strength and stiffness while the resin binds them together to create the shape. The other options describe different materials: carbon fibre is made from carbon, plastic would be the resin or a polymer matrix rather than the reinforcing fibre, and saying fibreglass is made of fibreglass would be circular. So the fibres themselves are glass.
