The correct answer is B. Biased
Step-by-step explanation:
In language, an antonym refers to a word that opposes in meaning to another word, for example, the word short acts as an antonym of the word tall or the word small acts an antonym to the word big. In the case of the word "objective" this word is used to purposes of goals as a noun as an adjective it describes ideas or elements that are based on facts rather than on feelings or prejudices and therefore, the word that is an antonym of this word is "biased" because this means based on personal judgments, feelings and prejudices which means "Biased" means the opposite or is an antonym of "objective".
