Final answer:
The best option to establish a non-binding agreement between organizations in early discussions is D. An MOU (Memorandum of Understanding), which outlines intentions without creating enforceable obligations.
Step-by-step explanation:
When organizations have agreed to cooperate and are in the early stages of discussion to define the responsibilities of each party without wanting to create a legally binding agreement, the best option would be D. An MOU (Memorandum of Understanding). An MOU is used to outline the intentions of the parties involved, describing the cooperative relationship rather than creating enforceable obligations. Conversely, an SLA (Service Level Agreement) typically includes specific performance criteria and is contractually binding, while an NDA (Non-Disclosure Agreement) is specifically used for confidentiality purposes. A BPA (Business Process Automation) refers to the use of technology to automate business processes and is not relevant to defining responsibilities in a cooperation context.
