1. The axial skeleton of the body comprised of cranial bones, facial bones, vertebral column, and thoracic ribs. Hence option (d) is the correct answer choice.

2. The first cervical vertebra that holds up the head is "Atlas".

3. The mandibular fossa and zygomatic process are the characteristic features of temporal bone of the cranium.

4. Red bone marrow is present in the epiphyseal ends of the long bones, and has primary function to produce red blood cells (RBCs) via they stem cells found in their myeloid tissue. Hence option (a) is the correct answer choice.
