Penalty for late filing of return under mvat act

I am a dealer eligible for for 704. The return for April to June 2015 was not filed by me before the due date, and I wish to file it now. However, while filing the return, it is giving me a choice to choose my fine. The options available are 1)5,000 2)2,000 3)1,000 Which amount is applicable to me? I wish to file the return today, that is 06/08/2015. Also, please provide reasoning so I can derive answers by myself from now on. Thanks Harshavardhan
