Correct answer: A — Mineral trioxide aggregate (MTA)

MTA (mineral trioxide aggregate) is the current gold standard for retrograde (root-end) filling during apicoectomy. It provides superior biocompatibility, excellent sealing ability, sets in the presence of moisture/blood, has antimicrobial properties, and promotes cementogenesis and bone regeneration. It has largely replaced amalgam and Super-EBA for this indication. Newer bioceramic materials (e.g., Biodentine, EndoSequence root repair material) are alternatives.
