Explanation / Answer

[1] (e) GUI seems to be the most appropriate choice

[2] We use interactive. Batch doesn't require manual interaction. Example of Batch processing is running bulk update queries on databases. Example of Interactive processing is booking a hotel on a web portal.

[3] (d) List of threads

[4] Context switching is overhead because it is cycles (time) that the processor is being used but no user code is executing, so no directly productive computing is getting done. Example: shell

[5] (c) Waiting for I/O service
