Which of the following is an example of data in process?

The correct choice is all of the above. Each example provided illustrates a scenario in which data is actively being processed.

When considering "data in process," it refers to information that is being actively used, manipulated, or is currently in transit to fulfill a function within a system.

For example, a food order placed through Uber Eats is being processed by the application and involves various activities like confirming the order, calculating the total cost, and relaying this information to the restaurant and the delivery person. This clearly indicates that the data is currently in a state of processing.

In addition, a password that has been submitted for authentication is also an example of data in process. When the password is submitted, it is being processed by the authentication system to verify the identity of a user. This data is not at rest; it is being actively evaluated to grant or deny access.

Similarly, a username submitted for authentication undergoes the same scrutiny as the password. The system processes this information to accurately identify the user.

Therefore, all the listed scenarios represent examples of data actively being processed, making the best answer inclusive of all options.
