The Correct option is A
Explanation and High Yield Points:
Nerve fibers Pulp and Dentin entering the teeth have been identified histologically as myelinated A-fibers and unmyelinated C-fibers. These fibers are grouped in bundles and enter through the apical foramina of the teeth, passing through the radicular to the coronal pulp where they fan out and diverge into smaller bundles.
Nerve divergence continues; individuals-fibers within small bundles lose their myelin sheath and divide repeatedly before finally ramifying into a plexus of single axons known as the subodontoblastic plexus or plexus of Raschkow.
The exact function of this plexus is unknown, as is the changing configuration of the plexus with dentin formation." From this plexus nerve fibers are distributed toward the pulp-dentin border with terminals showing a characteristic bead-like structure.
