Architectural stone selection — property required for ornamental work For detailed carving and ornamental stonework, the stone should primarily be:

Introduction / Context:
Ornamental stonework includes intricate carvings, moldings, and sculptures on facades and interiors. The ease with which artisans can shape the stone without chipping or splitting depends on the stone’s texture and hardness.

Given Data / Assumptions:

• Focus on workability and finish quality, not just strength.
• Common ornamental stones: marble, sandstone, limestone—generally workable and fine-grained.
• Carving requires tools to remove material cleanly.

Concept / Approach:
A moderately soft, homogeneous, fine-grained stone allows smooth tool action and fine detailing. Excessively hard stones (e.g., granites) resist carving, cause tool wear, and risk edge spalling. Uniform texture minimizes unexpected fracture paths.

Step-by-Step Solution:
Prioritize machinability and detail retention for ornamental work.Relate machinability to moderate softness and fine grain.Choose the option emphasizing softness and uniformity.

Verification / Alternative check:
Historic monuments often use marble or fine limestones for statues and ornament due to ease of carving and polish.

Why Other Options Are Wrong:
Hard only favors wear, not carving. Light/heavy weight alone does not ensure workable texture or finish.

Common Pitfalls:
Equating durability with suitability for fine carving; hard stones are excellent for steps or paving but not intricate detailing.

Final Answer:
Soft and uniformly fine-grained to permit carving
