Correct answer: C — Stainless-steel crown with glass ionomer cement lining

For MIH-affected permanent first molars with significant post-eruptive breakdown (PEB) but vital pulp, a stainless-steel crown is an excellent interim restoration. It provides full cuspal coverage protecting the hypomineralised enamel from further breakdown, controls sensitivity, and maintains the tooth until a definitive permanent restoration can be placed when the child is older. The SSC is lined with GIC for insulation and fluoride release. Conventional restorations (composite, amalgam) often fail in severely affected MIH molars due to poor enamel bond strength.
