What is true about laminated glass?

Laminated glass is designed with an inner layer of polyvinyl butyral (PVB) or another interlayer material that binds the glass layers together. This construction allows laminated glass to remain intact even when cracked. When the outer glass layer is impacted, the inner layer provides structural integrity, keeping the shards of glass adhered to the interlayer, thus reducing the risk of injury. This property makes laminated glass particularly valuable in safety applications, such as in vehicles and buildings, where preventing dangerous glass fragments from scattering is crucial.

The other options do not accurately describe laminated glass: it is not a single piece of glass, as it consists of multiple layers; it is designed to minimize sharp shards when broken; and it is frequently used in safety-related contexts, countering the claim that it cannot be used in such applications.
