Answer: b. in real time
Explanation:
When something is said to operate in real time, it means that is is happening instantaneously. Networked organizations that are so closely linked that their actions are seen instantaneously are therefore operating in real time.
These organizations can be in multiple countries but doing work on a similar platform. For instance, people around the world could be working on a single Go-0gle Sheets file and seeing the changes they all make in real time.
