Answer: B
Soda glass is so called because it is made using soda, that is sodium carbonate.
It is a soda-lime-silica glass, melted from sand, sodium carbonate and limestone in roughly the proportions 75:15:10. The soda lowers the melting point of silica from about 1,700 °C to a workable temperature, and the lime keeps the glass from dissolving in water.
