You have multiple SharePoint 2010 sites based on the same site definition. You need to plan a strategy to update the property value for a Web Part specified in the site definition for all existing sites. You must accomplish this with a minimum of developer hours.
Which strategy should you recommend?
A. Update the site definition to specify the new property for the Web Part and deploy it through a feature to each of the sites.
B. Create a delegate control with the updated value and deploy it through a feature to each of the sites.
C. Copy an update to the Web Part into the global assembly cache (GAC) and perform an IISReset.
D. Use a Power Shell script to iterate through the sites and update the property.
