Solution
The correct option is C Hypapophysis The first two or three lumbar vertebrae have another unpaired additional process, the hypapophysis, that extends downwards from the mid-ventral part of the centrum. This aids in muscle attachment. Haemal spines and chevron bones are examples of hypapophysis. The lumbar vertebrae have a neural spine that projects upwards and forwards.
