How should the Admin improve this process so the Configuration Attribute retains its value upon Renewal?

Universal Containers requires sales reps to choose a Square Footage value on the Configuration Attribute on one of the bundles to hide Product Options that are incompatible for the selected square footage. When the sales reps re-configure the bundle on a Renewal Quote, the Square Footage value that was set on the Configuration Attribute of the original Quote is reset to its default value. Currently, the sales reps must select the square footage again on the Renewal Quote.

How should the Admin improve this process so the Configuration Attribute retains its value upon Renewal?
A . Set the Renewed Asset lookup field on the renewal Quote Lines to reference the original Assets.
B . Create a Twin Field of the Square Footage field on the Quote Line object.
C . Set the Renewed Subscription lookup field on the renewal Quote Lines to reference the original Subscriptions.
D . Create a Twin Field of the Square Footage field on the Asset and Subscription objects.
