B. Three in each quadrant

D. Five in each quadrant

The correct answer is D. Five in each quadrant.

At birth, the alveolar processes, are called gum pads. Dental groove divides gum pad into labial and lingual parts. Transverse groove further divides gum pad into ten segments in each jaw. Each of the

segment houses a developing tooth sac. The transverse groove between canine and first molar called lateral sulcus, is helpful in predicting inter-arch relationship. The maxillary arch is wider and longer than its counterpart. The gum pads contact the mandible arch around the molar region and space between the upper and lower gum pads in anterior region. This space between upper and lower gum

pads is called an infantile open bite.
