Tax Planning: Convert FNO profits to STCG

I have one doubt. I heard, BTST trades come under business income. So we need to pay 30% tax, even tho, they are kinda technically STCG.

So, what will happen in this case?

I am a bit confused, Zerodha founder says, BTST needs to pay 30% tax, but Zerodha Tax P&L show BTST trades under “STCG”…so how much tax needs to be paid on BTST?

This also seem like a kinda off BTST trade, since ur selling the stock next day.
