a

b
the salamander does not produce an amniotic egg.

c
the leopard does not walk on four legs.

d
the lamprey does not have a vertebral column.

A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.

In this set of examples the answer is:

D) The lamprey does not have a vertical column

Lampreys have a notochord that remains throughout life, but they have primitive vertebrae made of cartilage. Lampreys have vertebral arches, but nothing resembling the vertebral bodies found in all higher vertebrates. Even the arches are discontinuous, consisting of separate pieces of arch-shaped cartilage around the spinal cord in most parts of the body, changing to long strips of cartilage above and below in the tail region.
