The MOST effective way to achieve reuse on an OO project is:

A.
Develop a persistence layer that makes it easy for the model and view layers to reconstitute
business objects.

B.
Keep the business rules as stored procedures in the database and develop a common lookand-feel framework in the view layer.

C.
Develop a model layer that makes it easy for the view layer to reuse the persistence layer.

D.
Keep business rules in the model layer and develop a common look-and-feel framework in the
view layer.
