Dal seems the comparitively right option. Alas, there should be facility to distribute the points because Pakshakaar is also right. 2 KudoZ points were awarded for this answer
very less response is there for marathi and sometimes no response at all. I think it is the problem with most regional languages as this site is not much popular, also marathi is too close to hindi and sanskrit.
But translation expected was in marathi and Dal/Gut/pakshakaar/samuh are not in much use in my language. Then also I'll thanks all the answerers who suggested many optional words. Now the problem is whom to select. Shall we wait some more time?
I think that vyakti and sanstha would connote an individual and organisation respectively whereas 'party' here seems to have been used in a different sense
