Pyrex glass.<\/p>\n<p>Pyrex glass is a type of glass that is resistant to thermal shock. This means that it can withstand sudden changes in temperature without breaking. Pyrex glass is made from borosilicate glass, which is a type of glass that contains boric oxide. Boric oxide makes Pyrex glass more resistant to thermal shock than other types of glass.<\/p>\n<p>Hard glass is a type of glass that is resistant to scratching. It is made from soda-lime glass, which is a type of glass that contains sodium oxide and calcium oxide. Hard glass is more resistant to scratching than other types of glass, but it is not as resistant to thermal shock as Pyrex glass.<\/p>\n<p>Flint glass is a type of glass that is colored with lead oxide. It is used to make objects such as vases, bowls, and windows. Flint glass is not as resistant to thermal shock as Pyrex glass or hard glass.<\/p>\n<p>In conclusion, the correct answer is A.
