The structure labeled I is the neural canal, or the spinal canal, or the vertebral foramen. It is the canal through which spines passes.

Now for the right answer to the above question:

  1. Option A is incorrect; the centrum is the center region consisting of both the canal and the body.
  2. Option B is correct
  3. C is incorrect; neural spines are the spines that carry impulses through the canal. The spines are not present in the diagram because it’s a detached and not an active bone.
  4. D is not the correct answer; transverse processes are the two longest extensions forming a downward angle.

You may please note that:

  • Transverse processes are the two longest downward extensions forming a triangle.
  • Neural canal is the pathway or channel through which the neural spines passes.
