What is the primary function of a leak-resistant zippered bag in the context of funeral practices?

The primary function of a leak-resistant zippered bag in the context of funeral practices is to contain a dead human body and any associated fluids. This type of bag is designed specifically for the sensitive nature of handling deceased individuals, ensuring that bodily fluids do not leak or escape during storage or transportation.

These bags are crucial for maintaining hygiene and dignity in funeral practices. They are typically used by funeral homes, hospitals, and during the transport of the deceased to ensure compliance with health regulations and to protect the environment from potential contamination. The design of these bags includes features that prevent leakage, which is essential during any handling or transportation process.

In contrast, while other options mention various aspects of funeral practice, none serve the specific function of containing both the body and fluids in a manner that addresses health and safety protocols, making choice B the most appropriate answer.
