Correct answer: C — Resin-modified glass ionomer restoration

Resin-modified glass ionomer is useful for cervical/root caries where moisture control is challenging and fluoride release is advantageous. A porcelain veneer or gold onlay is unnecessarily invasive for this shallow cervical lesion. The pearl is that material selection should match lesion location, isolation, caries risk, and functional demand.
