You create a Microsoft Windows SharePoint Services site that contains a content type named Proposal. The Proposal content type is applied to lists that are named within the site collection.

You need to update the Proposal content type to include a new column. You also need to ensure that the existing lists display the new column.

What should you do?

A.
Modify the Proposal content type to include the new column, and then push down the change to all content types that inherit the Proposal content type.

B.
Modify the Proposal content type to include the new column, and then write code to install and activate the content type on all sites in the site collection.

C.
Modify the Proposal content type to include the new column, and then write code to add the column to all lists to which the Proposal content type is applied.

D.
Create a new content type that is based on the Proposal content type and contains the new column. Deploy the new content type to all sites that use the Proposal content type, and then move the Proposal content type to the _Hidden content type group.
