Can somebody tell us why our project got rejected even though it's not copied, I have explained my work and thought in the loom video too

Hi Team, Please help me understand why two of my projects have gone rejected even though I had worked on them on my own. In my loom video also I have clearly explained how I found the output and everything still it got rejected. For proof of my work I've also given the link of excel file where I have made the analysis, still without any explanation they have got rejected. Please help me with this as now I don't know what exactly I have to do so that it gets approved. Thanks, Anjali kumari
