Best answer
Correct option is (a) silica

To explain I would say: The main component of glass is silica. The principal ingredient of glass is silica derived from sand, flint or quartz. Silica can be melted at very high temperatures (l723°C) to form fused silica glass which, because it has a very high melting point, is used for specialized applications including some laboratory glass.
