Explanation

The correct options, B, C, and D, describe specific functionalities of the <ltng:require> tag, such as ensuring scripts are loaded only once, controlling the order of loading, and allowing parallel loading of scripts. Option A is incorrect because the tag does not load files from Documents, and option E is incorrect as it pertains to loading scripts from external sources, which is not a primary capability of this tag.
