a. finalis.
b. medullaris.
c. equine.
d. caudalis.
e. sacralis.

I believe the correct answer from the choices listed above is option B. The tapered, conical inferior end of the spinal cord is called the conus medullaris.  The most distal bulbous part of the spinal cord is called the conus medullaris, and its tapering end continues as the filum terminale. Hope this helps.

Your answer is a. coordination
