Most Liquid Options on Indian market and broker

I am not active in Indian market and appreciate if somebody can recommend me
1) Most liquid Options in the Indian market? Are they
Options on Index Futures?
Options on Index ETFs?
Options on Equity
Options on Commodity Futures

2) Best broker platform
- Leverage for purchasing stock
- Platform which can put complex options trades like
- Spreads / Covered calls / Condors etc/ Collar

Something as good as Options Express in USA

Thanks in advance

I have tried many br0kers, and there is not much variety with respect to trading platforms and all are similar. Angel Broking looks good as of now with reasonable brokerage.
All the br0kers are regulated. Max leverage is 1:4 which can be flexible depending on your turnover.
Some br0kers offer commodity futures and Angel is one of them. Nifty futures and options are traded the most.
