A company is in the process of combining the human resources and marketing departments. Which of the following describes this change?

A business process change refers to modifying how work or workflows are performed, not to restructuring the reporting lines or grouping of departments.

A business merger involves two legally separate companies combining into one entity, which is not the case when two internal departments are consolidated.

An internal reorganization refers to a structural change made within a single organization - such as merging, splitting, or realigning departments - without any involvement of outside companies. Combining HR and marketing falls squarely into this category because both departments already belong to the same legal entity and no external boundaries are crossed.

An interorganizational change involves coordination or structural shifts that span multiple distinct organizations, whereas this scenario is confined entirely within one company.
