Prior to the creation of any content items based on templates, you have taken over the creation of data templates from a previous Developer. Based on the design plan, two templates were created, ItemA and ItemB. Both templates have three identical fields: Title, Subtitle, and Description. Based on Sitecore best practices, how would you improve the template design?

A. Set the template for ItemB as a base template for ItemA and set the template for ItemA as the base template for ItemB to ensure proper inheritance.
B. Set both templates to inherit from a new base template with the three duplicated fields, removing the fields from the existing templates.
C. Delete the templates and start over again with new templates, one for the three duplicated fields and one for all the other fields from ItemA and ItemB.
D. Set the template for ItemB as the base template for ItemA's template and delete the duplicated fields from ItemB's template.
