Answer:

The oldest known type of arch is the Corbel arch.

The oldest known type of arch is the corbel arch. This type of arch involves balancing a series of horizontal stone courses starting at the walls' spring to create an opening with a curving bottom that redistributes weight. The corbel arch supports the framework at the top of a building by using this method.

Many locations around the ancient Mediterranean feature corbel vaults and arches. Additionally, several pre-Columbian Mesoamerican structures and historical/regional architectural styles are characterized by their use of corbeled arches.

Therefore, the correct answer to the question is option a: Corbel arch.
