Define Custom Big Objects: No package.xml found

Question

I am working on the

Developer Intermediate Big Object Basics Define Custom Big Objects

I am not able to finish the challenge because I can not upload the zip file successfully through workbench. I select the options for:

Check Only && Single Package

This is the structure of my zip file

Here are the xml files: rider_history__b.object
