The correct option is A condyles
The structures connecting the skull with the vertebral column are known as occipital condyles.
These are the projections on the occipital bones. At the posterior end of the cranium there are 2 rounded occipital condyles in mammals and amphibians. They attach to the first vertebrae.
The ear ossicles are present in the skull. They are also called auditory ossicles. These are 6 in total- 3 in each ear- 2 malleus (hammer), 2 incus (anvil), 2 stapes (stirrup).
The vertebral column consists of 26 bones known as vertebrae.
