A personal fall arrest system consists of which of the following components?

A personal fall arrest system is designed to safely stop a person from falling while working at heights. The system must effectively arrest the fall and minimize the risk of injury. The correct option includes an anchorage, connectors, and a body harness, which are essential components of a complete fall arrest system.

The anchorage is a secure point to which the system is attached, ensuring that it can safely support the fall arrest forces. Connectors, such as carabiners, are used to link the worker's body harness to the anchorage or other components of the system, ensuring a secure connection. The body harness is worn by the worker and is designed to distribute the forces of a fall over the body, offering maximum protection and minimizing the risk of injury.

Each of these components plays a critical role in fall protection; without any one of them, the system would not function properly or provide adequate safety. This comprehensive approach makes option C the correct answer.
