Correct answer: C — They are cytoplasmic extensions of ameloblasts responsible for enamel rod (prism) formation
Tomes processes are cytoplasmic extensions of secretory-stage ameloblasts that are directly responsible for the deposition and organisation of enamel rods (prisms). The shape and orientation of the Tomes process determines the characteristic keyhole or fish-scale cross-sectional pattern of enamel rods. The distal (secretory) face of the Tomes process produces the rod enamel, while the proximal face produces the inter-rod enamel. They are resorbed during the transition from secretory to maturation stage.
