Construction (second occurrence) most closely refers to:

• A. A representation of a plan used in real estate
• B. A ceremony
• C. The process of moving soil
• D. The act or business of building things, especially structures

Answer: (D)

The word here points to building activity. Construction most closely means the act or business of erecting structures—the process of building, coordinating crews, and managing the building project. That sense fits when you’re talking about how something is put up or developed, rather than a ceremonial event or a plan/drawing. It’s also distinct from the idea of moving soil, which would be described more specifically as earthmoving or excavation. So the sense that best matches is the building work and industry behind creating structures.
