I am actually new in options trading I don’t know much more about options but one of my friend do trades on Sensex whe i see option trading section there is only nifty, bank nifty and fin nifty. After some research i came to know that dhan also provides bse index trading but it should mention over there.
While someone from @Dhan can answer regarding your question for dhan android app,
I suggest you to take a look into exclusive options trader app by dhan, which has pretty much all common index and strikes, and will be more easy for options trading than the regular one.
The top bar has the most commonly traded indices. We have all the indices if you scroll down, and you can get their option chain once you click on the specific index.
Also, you can use the search bar to get the option chain for your desired index or stock
