Option 1: Soda glass is a type of glass that is commonly used in the manufacturing of beverage bottles and windows. However, it is not suitable for bulletproof screens as it is not strong enough to withstand the impact of a bullet.

Option 2: Pyrex glass is a type of borosilicate glass that is known for its high resistance to thermal shock. While it is not specifically designed for bulletproof applications, it is stronger and more durable than soda glass. It can potentially offer some level of protection against bullet penetration, making it a viable option for bulletproof screens.

Option 3: Jena glass, also known as quartz glass, is a type of glass that is highly resistant to temperature changes and chemical corrosion. Although it is a strong and durable material, it is not typically used in the production of bulletproof screens.

Option 4: Reinforced glass, also called laminated glass, is a popular choice for bulletproof applications. It is made by sandwiching layers of glass with a layer of plastic in between. This construction enhances the strength and resistance of the glass, making it capable of stopping a bullet.

The correct answer is option 2, Pyrex glass. While not designed specifically for bulletproof purposes, it offers a higher level of
