Answer 1

Answer: (D)

Pterygoid

• Facial bones are 14 in number they are, inferior nasal concha (2), lacrimal bones (2).
• Mandible, maxilla (2), nasal bones (2), palatine bones (2), vomer, zygomatic bones.
• The pterygoid is a paired bone forming part of the palate of many vertebrates, behind the palatine bones. In humans, it becomes the pterygoid processes of the sphenoid bone. Hence pterygoid is a bone of a skull.
  

So, the correct answer is 'Pterygoid'.
