Which of the following is a standard method for packaging fragile items?

Using protective wrapping materials is a standard method for packaging fragile items because these materials are specifically designed to cushion, support, and protect delicate products from potential damage during transportation and handling. Protective wrapping materials, such as bubble wrap, foam, or specialized packing paper, help absorb shocks and impacts, preventing breakage or scratches that could occur if the item were to collide with other objects.

In contrast, using loose newspaper may not provide sufficient cushioning and can lead to ink transfer or damage to more sensitive surfaces. Applying duct tape is not effective for securing fragile items because it does not offer the necessary protective qualities and can be difficult to remove without damaging the packaging or the item itself. Leaving items unwrapped exposes them to a higher risk of damage from movement, environmental factors, or collisions, making it an unsuitable choice for fragile items.
