Arch Carries the thrust of Weight - Option D

An arch carries the thrust of weight to its sides. With a post-and-lintel, the horizontal part of the structure supports all the weight above it. The reason is that the post and lintel is a system of construction. In this the powerful parallel components are kept up by powerful upward components that has large cavities between them.

Therefore, an arch carries the thrust of weight to its sides for balancing purposes.
