Which approach should you recommend?

The IT, human resources, and legal departments in a large company each have site collections that run in
separate Web applications in a SharePoint 2010 server farm. You need to design a SharePoint information
architecture that will meet the following requirements:
All departments should use a consistent set of keywords. .Certain enterprise keywords must be shared across all
departments.
.The keywords should be managed dynamically.
.The keywords should be globally available to SharePoint service applications.
.The keywords should be able to be managed programmatically.
.The keywords management must use standard services and be maintained with built-in SharePoint 2010 administration tools.

Which approach should you recommend?

A.
Programmatically connect each Web application for all departments to the Global Managed Metadata shared service containing the common enterprise keywords.

B.
Programmatically add the site collection containing the common enterprise keywords list to the Web applications for all departments.

C.
Create a managed metadata term set of all of the common enterprise keywords and deploy it as a feature to the farm.
Programmatically activate the feature in the Web application for all departments.

D.
Create a managed metadata term store of all of the common enterprise keywords and deploy it as a feature to the farm.
Programmatically activate the feature in the Web application for all departments.
