Which itr to file to use if i have salary, speculative income and f&o losses

I have salary (<50 Lkahs), equity/trading profit and F&O loss (turnover is less than 1 crore and profit is negative or less than 8%). Two questions

1. Which single ITR to use for all three of the above

2.  Since F&O is loss (business income < 8%) do I need to get my books audited. BTW there was 1 single trade in F&O which caused loss of around 3 lakhs....

Thanks
