The correct answer is C. Do or make
Step-by-step explanation:
In language, a root word or basic word refers to a word that is used as the base to create more words usually by adding other syllables or letters before or after the rood word which are called prefixes or suffixes. In the case of the root word "fec" this word derives from Latin and means to do or to make. For example in the words "affect" that means to do something to someone or the word "perfect" that describe something that is thoroughly or completely done/ make. Therefore, the meaning of the root word "fec" is to do or make.
