The app.yaml handler property for static directories is "static_dir," meaning that B static_folder, C: dir_static, and D: folder_static are all incorrect options.

B: static_folder and D: folder_static are not valid options because they do not match the proper naming convention of "file_name_property."

C: dir_static is incorrect because it does not specify that it is a static directory. Additionally, it is important to note that the structure and formatting of the app.yaml file is crucial in order for the App Engine to properly handle static files.
