Your subject needs to be larger. You have too much negative space. To freeze the motion you need faster shutter speed and a burst of shots. Once or a few will come out without motion blur.
I think that generally speaking, your image of the drone is too small in the frame. Currently, it is hard to determine what it actually is! Your composition would play a part here as well. It could be positioned better in the frame of the camera.
Secondly, I also wonder about its commercial use. Who would use this? There are a lot of examples in stock on drone photos:
You should remember that we require the refusal reason that Adobe gave you. That is of a great help and takes away much of the guesswork. We will give anyhow all reasons we see, including the commercial value.
The commercial value is kind of appreciation, and one of the pictures, I have submitted and where I suspected low commercial value, sells fine. But still, I agree with @Nancy OShea that this asset here has little commercial value and I agree with @Jill_C that more of your subject should be in the frame to make this an interesting picture.

It's a tiny, blurry unidentifiable object. You would have needed to fill the frame with the object and use a much faster shutter speed to create an acceptable image.
Fill the frame, yes. Faster shutter speed: I don't think so. I suspect it's more the overall quality: artefact in the blurred part, small object, pole in the upper part etc. It simply does not look right, interesting and well framed. Looking on my iPad at higher magnification, I see multiple artefacts.

You can't make money from stock pictures of someone else's property - the Drone maker owns the rights. Also the composition is not great - the drone is far too small. You didn't tell us the reason for rejection - IP, quality - both of these apply.
