Hi,
This plugin can remove data based on the SQL queries data interconnectivity. There is no way to use that method on wp-options table. There is no 100% way to automatically detect such data in that table.
But, I have another plugin called [b]Smart Options Optimizer[/b] that is designed for this purpose: [url]http://d4p.me/ccsoo[/url]. This plugin runs analysis of the usage of wp-options records over period of time and determines if some of them are not used at all, recommending removal. It needs to run for several hours so it can gather as much usage data as possible to determine unused records and to also recommend auto load status for wp-options data. Check out the video here:

Plugin is very effective, but requires a bit of patience to analyze data. There is really no other way to know what belongs to what plugin in wp-options table, even manual analysis is a problem there. This is the best solution I know of.
