Correct answer is (c) relative_assets
The best explanation: sass_dir gives folder name for the sass or SCSS style sheet to be stored. The output_style property specifies compiled CSS output. The relative_assets property specifies the output path in the compiled CSS. If it is set to true, the http_path property will be ignored and the compass will generate a relative URL. line_comments specifies whether compass should generate line number where style sheets rule are defined.
