The correct answer is A. Dawn and Cara took me out to dinner for my birthday.
Step-by-step explanation:
Sentence using the active voice follow the traditional structure subject+verb+objec/complement. This does not occur in the passive voice that begins with the object then includes the verb (auxiliary verb+ past participle) and finally the subject. Additionally, in the active voice, the emphasis is on the subject and action rather than the object.
Sentence A is the only one using the active voice because it follows the grammatical structure of this voice as "Dawn and Cara" is the Subject, "took out" is the Verb and "me" is the Object or entity affected by the action. Also, other options begin by the object "I" which means they are in passive voice rather than active voice.
