The correct answer is: A. sand, soda, limestone
Sand is the main ingredient in glass, making up about 70% of the total weight. Soda ash (sodium carbonate) is the second most important ingredient, making up about 15% of the total weight. Limestone (calcium carbonate) is the third most important ingredient, making up about 10% of the total weight.
The other options are incorrect because they do not include all three of the main ingredients in glass. Option B does not include limestone, option C does not include soda ash, and option D does not include sand.
Sand is a type of sediment that is made up of tiny pieces of rock. It is the most common raw material used in glassmaking because it is abundant and relatively inexpensive. Soda ash is a chemical compound that is used to make glass more durable and resistant to breakage. Limestone is a type of rock that is used to make glass more stable and less likely to crack.
In addition to the three main ingredients, other materials may also be added to glass to give it certain properties. For example, iron oxide can be added to make glass green, while cobalt oxide can be added to make it blue.
