A Civil 3D object property set that governs how the object looks and behaves.

• A. Template
• B. Style
• C. Master
• D. Context

Answer: (B)

The central idea is that a style in Civil 3D defines both how an object is drawn and how it behaves. A style bundles the visual rules (color, layer, line type, visibility in different views, symbology) with behavior rules (how data is displayed, labeling, how the object interacts with other tools). Changing the style changes the appearance and the way the object functions without altering its geometry. For example, applying a different surface style can switch from a simple shaded view to a contour-and-color display with labels, and switching an alignment’s style can change how it’s shown in plan while keeping the same geometry. A template sets defaults for new objects, not the properties of an existing one, and terms like master or context aren’t used to describe this particular object property set.
