B) Silica glass

Question

Quizplus · Accepted Answer

Ordinary glass has a higher coefficient of thermal expansion than silica glass. This means that it will expand and contract more significantly when exposed to changes in temperature, which can lead to cracking or breaking. Silica glass, on the other hand, is more resistant to thermal expansion and is often used in high-temperature applications.
