Correct answer: D — Maxillary first premolar
The maxillary first premolar is the tooth most frequently fractured during extraction due to its thin, often bifurcated roots (buccal and palatal roots in approximately 60-70% of cases) that may diverge significantly. The thin roots are prone to fracture, especially if excessive force is applied in one direction without adequate luxation. Controlled, gradual buccal-palatal movements with appropriate forceps (No. 150) and slow delivery reduce fracture risk.
