Key benefits of reinforced concrete (RCC): Which of the following advantages are correctly attributed to RCC as a structural material?

Introduction / Context:
Reinforced concrete dominates building and infrastructure construction because it integrates the compressive strength of concrete with the tensile capacity of steel. Understanding its advantages informs material selection and conceptual design choices.

Given Data / Assumptions:

• Normal construction environments.
• Proper mix design, detailing, and curing assumed.

Concept / Approach:
RCC forms a monolithic system via cast-in-place continuity; it is inherently fire resistant due to concrete cover, durable when properly proportioned, and can be cast into a wide range of shapes. Lifecycle economy follows from robustness and comparatively low maintenance if exposure conditions and detailing are addressed.

Step-by-Step Solution:
Recognize that all listed attributes are established RCC benefits.Select the comprehensive option that includes all the listed advantages.

Verification / Alternative check:
Codes and handbooks consistently cite these benefits, especially for multi-storey buildings, bridges, tanks, and foundations.

Why Other Options Are Wrong:
Any single attribute alone is incomplete and understates RCC's versatility.

Common Pitfalls:

• Ignoring durability detailing (cover, crack control) which is essential to realize these advantages.

Final Answer:
All the above
