The correct answer is C. Revised
Explanation:
In language, the meaning of a word is often defined by the meanings of both the root word (the main part of a word) and the prefixes or suffixes added to it (syllables before or after the root word).
In this way the word "revise" means to change, modify or alter but by adding the suffix "-ed" the meaning to changes "to have changed" this can be explained as the suffix "-ed" can be added to different verbs to create the past simple of the verb or the past participle that are both forms of verbs that express an action has finished and therefore the word "revised" means "to have changed, to have modified or to have altered".
