[2025-10-02T02:58:28.452558] [PI reasoning] **Evaluating canal incidence**

The question focuses on the incidence of an extra canal in the mandibular first molar, which relates to dental anatomy. Typically, mandibular molars have two mesial canals and one distal canal, with an extra canal found about 5% of the time. However, literature indicates that 4 canals are present in 29-35% of cases. Based on this, the best choice would be approximately 30%, making C the optimal answer, supported by references.
