Interest on Unsecured loan from HUF

Hello everyone,

I have taken 30 lacs loan from my HUF for FnO trading. I purchased Liquidbees using that amount, and pledging it with my broker for Margin, and using that margin for building positions in Options.

1) Can I pay interest to HUF for this loan amount ?

1a) if yes at what rate ?

2) Can i deduct this interest amount from my profit as expenses ?

Thanks in Advance
