Cleaning options

I am using a clean options plugin. It came up with these results. Is it safe to delete these?

The following Options appear to be orphans. When shown, non-selectable Options are known to have been created from files present during upgrade or backup, or are legitimate options that do not “fit” the search for get_option or get_settings.
