During post insertion examination of a 3 unit ceramometal fixed partial denture. One of the retainers showed chipping of porcelain at the ceramometal junction. In order to avoid the problem the dentist must:
a. Reduce the metal to 0.3 mm.
b. Have uniform porcelain thickness.
c. Have occlusion on metal.
d. Keep porcelain metal junction away from centric contacts.***
