The correct answer is A) an animal having a backbone.

To arrive at this answer, you can break down the word "vertebrate" into its parts. "Vertebrate" combines the root "vertebr-" with the suffix "-ate."

1. The root "vertebr-" refers to "vertebrae" or the individual bones that make up the spinal column or backbone. Therefore, we can infer that the word "vertebrate" is related to something associated with a backbone.

2. The suffix "-ate" is a common suffix used to form nouns, adjectives, and verbs. In this case, it is used to form a noun.

By combining the root and the suffix, we can conclude that "vertebrate" refers to "an animal having a backbone." So, the correct answer is A) an animal having a backbone.
