If I wanted to figure it out, I'd add a hook to update_option, and
then have my hook run a debug_backtrace() to get the function call
stack. By examining that stack, you can determine what file made the
call to update_option, and if the file is in wp-content/plugins/*,
then it's a plugin's option and you'll know.
