Answer: (B)

Elevation drawings are critical in building construction as they provide a visual representation of the building's external appearance. These drawings display the facade of the structure, including details such as windows, doors, rooflines, and exterior materials. Elevation drawings serve multiple purposes, including helping architects and builders understand how the building will look in its environment, ensuring compliance with design aesthetics, and aiding in the planning of any required landscaping.

The detailed visual aspect offered by elevation drawings is essential for communicating design intent to clients, stakeholders, and regulatory bodies. By showcasing vertical dimensions and the interplay of different architectural elements, these drawings allow for a comprehensive understanding of the final product before construction begins, thus playing a vital role in the overall design process.
