____ software manages word processing files and allows users to save,index,and quickly retrieve files.?

Question

A-Document management
B-Docket control
C-Case management
D-Database

Answer 1

Your question is unclear. There are millions of those software depending on which scale/interfacing/file types you are talking about.
Can you please clarify? Thanks.

Answer 2

Of those listed, my answer would be A) document management.

However, doc management solutions can manage many more doc (file) types than word processing files.

And usually doc management solutions have databases behind them to manage indices etc.

And doc management solutions can also be used for case management and/or docket control.

So your question is pretty vague on context.
