Fill in the blank with a suitable preposition.
She came to the party _______ auto.
The preposition ‘by’ is used to show how or in what way something is done, especially to denote the transport that is used for travelling. In the given context the person uses an auto to travel, therefore ‘by’ is the apt answer. Thus option A is correct. Whereas ‘with’ in the given context would mean in the company of someone. Since the auto is not a person and cannot accompany the person to the party option C is incorrect. Similarly ‘for’ cannot be used in the sentence because ‘for’ is used to denote why something is done or for whom. The party is not conducted for the auto, therefore, option B is incorrect. The preposition ‘of’ is used to express belonging, which is inappropriate here because the party doesn’t belong to or originates from the auto. Thus option D is incorrect.
