The correct answer is D. One or more syllables placed at the end of a base, or root word
Step-by-step explanation:
In the English language and many other languages, words are formed based on three different sections that include root words, prefixes, and suffixes. In the case of root words, these are basic words and the center of word-formation. On the other hand, suffixes and prefixes refer to one or more letters/syllables added to a root word, in this way, suffixes are those syllables or letters added after a root word and prefix those added before or at the front of a root word. For example, in the case of the word "preview" the root word is "view" that means see and the prefix is "pre" that means before. Considering this, a prefix is one or more syllables placed at the end of a base, or root word.
