You have a social networking site in SharePoint 2010 that allows users to post content for

all other users to view. Users have read-only access to documents that they did not upload
themselves. You are designing a way for users to easily flag content as objectionable so
that the site administrators can evaluate and remove this content as necessary. You need to
add this objectionable content functionality to all document libraries. Which approach should
you recommend?

A.
Add a custom field to the base document content type and an event receiver to the
document library that will execute the objectionable content functionality.

B.
Add a button to the ribbon associated to document libraries, which will execute the
objectionable content functionality when clicked.

C.
Add a dialog to the site default page that will walk the user through how to report
objectionable content.

D.
Modify the system files within the layouts directory that are used to render the form
pages.
