Neutral word i think if you are talking diction and dont want give any emotion
The correct option is D) “Both A & B are incorrect.” Both sentences are incorrect because of the use of the phrasal verb “stand up”. The meaning of the phrasal verb is to make yourself into an upright position and a bike cannot “stand up”. The correct verb would be “stand”, which means to take or maintain a specified position.
The rest of the options are incorrect since the phrasal verb "To stand up" is on both sentences.
