Final answer:
BPMN is a visual language for modeling business processes and is intended to facilitate human understanding, rather than being directly executable. The correct option is C.
Step-by-step explanation:
BPMN stands for Business Process Model and Notation. It is a visual language designed for businesses to model and document their business processes. BPMN provides a standard way for all stakeholders to understand the various processes using diagrams which represent the steps of a workflow.
However, BPMN models are not directly executable; they are intended primarily to facilitate human understanding and are usually accompanied by executable languages like BPEL (Business Process Execution Language) when automation is desired.
