Internal Redundancy is described as:

Internal Redundancy is described as:

• A. Continuity of load path from span to span
• B. If one member fails, load redistributed to other members
• C. The three main components of a bridge
• D. Creation of multiple load paths by elements that are mechanically fastened together

Answer: (C)

Internal redundancy means the structure has multiple internal load paths so that if one member fails, the loads can be taken by other members. The option that best captures this is the idea that if one member fails, the load is redistributed to the remaining members. This capability helps prevent sudden collapse by spreading forces through alternate paths. The other descriptions don’t describe this redistribution behavior as the defining feature of redundancy.
