Final answer:
Monolithic constructions are the most susceptible to total failure resulting from the failure of a single component.
Step-by-step explanation:
The construction assembly that is the most susceptible to total failure resulting from the failure of a single component is a **monolithic construction**. Monolithic constructions are structures where different components are integrated into a single, unified whole, such as a building or a bridge. If a crucial component in a monolithic construction fails, it can lead to the entire structure collapsing.
For example, in a building, the failure of a supporting column due to corrosion or structural weakness could cause the entire building to collapse. Similarly, in a bridge, the failure of one or more key structural elements, such as the main supports, can result in the complete failure of the bridge.
