Core built up on a molar tooth should preferably be done with a chemically cured composite as:
(A) Light cure resin lacks sufficient strength for a core (B) Core made with a light cure resin would be too opaque and esthetically unacceptable (C) core made with a light cure resin would be too brittle and would fracture easily (D) Its lower viscosity allows free flow of resin also around pins and post
(D) None
