What is the primary purpose of the International Building Code (IBC)?

The primary purpose of the International Building Code (IBC) is to establish minimum requirements for building safety, health, and welfare. This code provides a uniform set of standards that aim to protect public health and ensure the safety of structures by addressing aspects such as structural integrity, fire safety, sanitation, and accessibility. By creating these standards, the IBC helps ensure that buildings are constructed in a way that safeguards occupants and the general public against various hazards.

In relation to the other options, while aesthetic guidelines, energy efficiency, and land use regulations are important aspects of building design and urban planning, they do not fall within the core objectives of the IBC. The focus of the IBC is primarily on safety and welfare, making option C the most accurate representation of its fundamental purpose.
