Masonry walls are constructed from

• A. Natural stone laid with mortar
• B. Gypsum board
• C. Blocks with plaster
• D. Blocks with mortar

Answer: (D)

Masonry walls are formed by laying individual masonry units such as concrete blocks or bricks and binding them with mortar. The mortar fills the joints and bonds the units, distributing loads and resisting movement. This makes blocks with mortar the best description of a masonry wall, since it emphasizes both the units and the binding material that hold them together. Gypsum board is drywall used for interior finishing, not the wall’s actual masonry structure. Plaster is a coating applied over a substrate, not the wall’s main construction material. Natural stone laid with mortar is also masonry, but the common, general phrasing for this context is blocks with mortar, which covers the typical units and bonding method used.
