 # The furcations are likely to be farthest away from the cervical portion of the tooth in which of the following teeth?

A. Mandibular first molar

B. Mandibular second molar

C. Mandibular third molar

D. Maxillary first molar

The correct answer is C. Mandibular third molar. 

Both maxillary and mandibular third molar roots are noticeably shorter than on firsts or seconds. They are very crooked, often curving distally, and more commonly fused most of their length resulting in a long root trunk with the furcation located only a short distance from the apices of the roots.
