Which option best describes the primary function of bonding agents in the dentin bonding process?

Explanation:
The primary role of bonding agents is to infiltrate the conditioned dentin and interact with the exposed collagen to create a resin-reinforced zone—the hybrid layer. This hybrid resin-collagen layer forms a continuous micromechanical bond between the dentin and the adhesive resin, and ultimately to the composite. The smear layer and the etching step are addressed during surface conditioning, not by the bonding agent itself, so the most precise description is forming that hybrid resin-collagen layer.
