B Correct answer
Explanation

The 'using System' statement refers to the System assembly, which is a .NET framework library (dll). Assemblies are the fundamental deployment units in .NET, containing compiled code and metadata. Header files are a C/C++ concept, COM is a pre-.NET technology, and System is not an executable.
