IMO, for option trading Zerodha is the best. They charge 20 INR per trade plus statutory expanses irrespective of number of lots, whether 1, 10, 100 or 1000, however, if you plan to do more than 10 trades per day then RKSV, they charge 1947 INR for unlimited trades per month plus statutory charges. So the choice is yours.

equity intraday @ 500 per crs or 0.005 %
