Hi
and welcome in the forum. Options are an universe by its own and to learn about them takes time and patience. You can learn in this forum about many things when it comes to options and option trading.
As we do not know what you want to learn about options and option trading in specific and as you seem to be Indian, why not start here:
http://www.tradersedgeindia.com/beginners_guide_options.htm (Just make copy past to an other tab in your browser and you will be there, as at the moment hyperlinks are disabled in this forum for reasons we do not know at the moment)
If you went through that link, which was posted from a member here in the forum and I just saved it as a link, come back and let us know what you need next.
Take care / DanPickUp
