When connecting a personnel platform to the load line using a wire rope bridle, each bridle leg must connect to what component?

The correct choice is the master link because it acts as the central connection point for the bridle legs in a wire rope bridle system. When using a personnel platform, the bridle is configured to distribute the load evenly and securely. Each leg of the bridle attaches to the master link, which in turn connects to the main hook or load line. This arrangement ensures that the load is balanced and reduces the risk of accidents, which is crucial when personnel are being lifted.

In contrast, other components like the anchor point, hook block, and load pin are not intended for direct attachment of each bridle leg in this context. The anchor point typically refers to a structural location where a fixed connection is made, the hook block is generally used to manage the load line and does not serve as a bridle connection point, and the load pin is usually part of the load cell or weight measurement system, not a connection point for the bridle. The proper use of the master link is critical for maintaining safety and compliance with lifting operation standards.
