Animal Y is a vertebrate, and animal Z is an invertebrate.
Animal Y is an invertebrate, and animal Z is a vertebrate.

The statement that is best supported by the X-rays in the image is animal Y is an invertebrate, and animal Z is a vertebrate (last option).

Explanation:

X-rays are a type of electromagnetic radiation that allows internal imaging of a living organism or object. Higher density structures, such as bones and tissues with calcium, tend to appear light (radiopaque) and lower density structures dark (radio lucid) on x-rays.

In the image it can be clearly seen that animal Y has a radiopaque structure on the outside, but lacks a spine, while animal Z -a snake- has a visible spine.  According to this, the best option to describe the image is that animal Y is an invertebrate and Z is a vertebrate.
