desirable
adequate
energetic
consistent
Answer is Wrong!
Answer is Right!
The correct answer is C. Energetic.
An antonym is a word that means the opposite of another word. In this case, the word “indolent” means lazy or inactive. The word “energetic” means full of energy or active. Therefore, the word “energetic” is the antonym of “indolent.”
The word “desirable” means something that is wanted or desired. The word “adequate” means something that is enough or sufficient. The word “consistent” means something that is always the same or unchanging. None of these words mean the opposite of “indolent,” so they are not the correct answers.
