The wedge shaped bricks forming an arch ring, are called A. Soffits B. Voussoirs C. Haunches D. Spandrils

The correct answer is B. Voussoirs.

A voussoir is a wedge-shaped stone or brick forming part of an arch. The voussoirs are arranged in a radial pattern and are held together by gravity and the weight of the structure above them. The voussoirs at the top of the arch are called the keystone, and they are the most important voussoirs, as they support the weight of the entire arch.

The other options are incorrect. A soffit is the underside of an arch or vault. A haunch is the curved side of an arch. A spandrel is the triangular space between the arch and the enclosing wall.
