Bullet proof glass is made of thick glass sheet sandwiched by a layer of A. Steel B. Stainless steel C. High test plastic D. Chromium plate

The correct answer is: B. Stainless steel

Bulletproof glass is made of two or more layers of glass with a layer of transparent plastic or a polymer interlayer. The plastic interlayer helps to absorb the impact of a bullet and prevent it from penetrating the glass. Stainless steel is a strong and durable material that can withstand the impact of a bullet without shattering.

The other options are incorrect because:

• Steel is not as strong as stainless steel and is more likely to shatter when hit by a bullet.
• High test plastic is not as strong as stainless steel and is more likely to shatter when hit by a bullet.
• Chromium plate is not a strong enough material to withstand the impact of a bullet.
