Answer: Passive
Step-by-step explanation:
In the passive voice, the action of the verb is being performed on the subject unlike in an active voice where the subject performs the action on the verb.
A passive voice for instance is: The question was answered by Parrain. Here subject is being acted upon by the verb.
The above therefore is in passive voice as the action of the verb - has been offered - is being acted upon the subject who is Eric.
