a) Facial pulp horn may be exposed
b) Inclination of cervical enamel rods occlusally
c) Of marked cervical constriction
d) Prime contact is broad and flat

The correct answer is C. of marked cervical constriction.

Gingivally the enamel rods have an occlusal direction in primary teeth so bevel is not required as there will be no unsupported enamel rods. It is difficult to obtain gingival wall when lesion extends too far gingivally in primary molar due to the presence of marked cervical constriction.
