Answer: (D)

Verified step by step guidance

1. Step 1: Begin by understanding the anatomy of the hard palate, which is the bony structure forming the roof of the mouth. It separates the oral cavity from the nasal cavity.
2. Step 2: Identify the bones that contribute to the hard palate. The hard palate is primarily formed by two bones: the maxilla and the palatine bone.
3. Step 3: Focus on the anterior portion of the hard palate. The anterior part is formed by the palatine processes of the maxilla, which fuse at the midline to create the majority of the hard palate.
4. Step 4: Review the location and function of the other bones listed in the options. The zygomatic bone forms the cheekbone, the temporal bone is part of the sides and base of the skull, and the occipital bone forms the posterior base of the skull. None of these contribute to the hard palate.
5. Step 5: Conclude that the maxilla is the correct answer, as it forms the anterior portion of the hard palate through its palatine processes.
