Fibre glass A. Retains heat-longer B. Has a higher strength to weight ratio C. Is shock proof and fire retardant D. All the above

The correct answer is D. All the above.

Fiberglass is a material made from very fine glass fibers that are spun together to form a mesh. It is a strong, lightweight material that is often used in insulation, construction, and automotive applications. Fiberglass has a number of advantages over other materials, including:

• It is a good insulator, meaning that it can help to keep heat in or out of a building or vehicle.
• It is lightweight, making it a good choice for applications where weight is a concern.
• It is strong, making it a good choice for structural applications.
• It is shockproof and fire retardant, making it a good choice for applications where safety is a concern.

Fiberglass is a versatile material that can be used in a variety of applications. It is a good choice for applications where strength, lightness, insulation, shock resistance, and fire resistance are important.
