• A. Tempered Glass
• B. Safety Glass
• C. Laminated Glass
• D. Float Glass

Answer: (A)

Tempered glass is designed to break into many small, blunt pieces when shattered, rather than into large sharp shards. This rapid, widespread fracture happens because the glass is heat-treated to create surface compression and internal tension. That makes it especially suitable for inside and rear automotive windows, where small fragments reduce injury risk. Laminated glass, with its interlayer, tends to hold together at impact and doesn’t crumble into lots of pieces, which is why it’s typically used for windshields. Float glass is plain, untreated glass and doesn’t have this safety-fracture behavior. Safety glass is a broad term that includes tempered glass, but the specific description of fragmenting into many small pieces points to tempered glass.
