Final answer:
To use the Video Visit Tech Tool, one must have a KP account. An appointment is not necessarily required to use the tool.
Step-by-step explanation:
To use the Video Visit Tech Tool, one must have a KP account. This is because the Video Visit Tech Tool is a feature provided by Kaiser Permanente, a healthcare organization. Without a KP account, one would not be able to access the tool.
An appointment, on the other hand, is not necessarily required to use the tool. While it may be helpful to have an appointment scheduled for a video visit, it is not a requirement to use the Video Visit Tech Tool itself.
Therefore, the correct answer is option b) A KP account is required, but not necessarily an appointment.
