Which of the following are types of tie assemblies?

The correct selection identifies types of tie assemblies commonly used in scaffolding systems. The U tie, Box tie, and Trough tie are indeed recognized types of tie assemblies that play essential roles in enhancing the stability and safety of scaffolding structures.

The U tie is shaped like the letter 'U' and is used to secure scaffolding to the building structure, providing lateral support. The Box tie is a more complex tying system that can anchor scaffolding to the facade of a building at multiple points, which distributes loads effectively. The Trough tie is used to connect scaffolds to existing structural elements and is designed to hold loads while maintaining the scaffold's vertical and horizontal alignment.

In this context, the other groups mentioned contain terms that might not be widely recognized or accepted within scaffolding terminology. While other sequences may include terms that sound plausible, they do not align with the official classifications used in scaffolding practice, making the combination provided in the correct answer the valid one in terms of standardized construction practices.
