Correct answer: D — Combined erosive and abrasive tooth surface loss

Cervical wedge defects with acidic drink exposure and vigorous brushing suggest combined erosive and abrasive tooth surface loss. Enamel hypoplasia or dentinogenesis imperfecta would have a more developmental and generalised pattern. The pearl is to manage sensitivity while modifying diet and brushing technique to prevent progression.
