Show answer and explanation

Correct answer: (D) An object-oriented data model facilitating interoperability

Explanation

IFC provides a structured, vendor-neutral representation of building objects and relationships for exchanging information between applications. Thus D. It is not simply a modelling-precision algorithm, a spline program, or an energy-saving module.
