There are several words with similar (in some sense) meaning:
Options, Settings, Properties, Configuration, Preferences
English is n
One thing that I don't see in the answers here (although bobince alludes to it) is that you should consider what is typical for your environment/operating system. For instance on windows I think "Options" is the most common choice even though many programs use different words. Likewise "Preferences" for mac os. Android OS uses "Settings"
So bottom line, use what is most common for your environment.
