C Correct answer
Explanation

ISO 9126 (later superseded by ISO/IEC 25010) defines six main quality characteristics: Functionality, Reliability, Usability, Efficiency, Maintainability, and Portability. Supportability is not one of the original six characteristics in ISO 9126 - while it is a related quality attribute in other frameworks, it is not explicitly listed as a primary characteristic in the ISO 9126 standard. The other three options (Functionality, Usability, Maintainability) are all core characteristics in the standard.
