The correct answer is (a) http_path
Best explanation: http_path specifies a path to the project when running on a web server. It is set to/by default., so the path output will begin with /. E.g. background-image: url(“/image/hj.png”). Folder name for all the images to be stored is specified by images_dir. css_dir specifies folder name for CSS style sheets. sass_dir gives folder name for the sass or SCSS style sheet to be stored.
