Answer:
C) Some prefixes are added to the end of a root word.
Step-by-step explanation:
Prefixes are letters that are added to the beginning of a root word in order to create a word that has a different meaning. Therefore, by adding a prefix, we change one word into another one. Knowing the meaning of a prefix can help us figure out the meaning of the new word. For example, if we know that "un-" means "the opposite," then we can better understand what "unhappy" (not happy), "unable" (not able) and unpack (the opposite of packing) mean. However, prefixes are always added at the beginning of the word. When letter are added to the end of the word, these are called suffixes.
