Solution
The correct option is B Dentary
The single bone that makes up the anterior bone of mammalian lower jaw is the dentary. At its posterior end is an articular (condyloid) process, which articulates with a bone, called as squamosal in the upper jaw. The dentary also usually has an enlarged area at its posterior end, the coronoid process. This process provides attachment for muscles that participate in chewing.
