Answer:
The sentence which has a verb in the passive voice is the following one:
The potholes on our street will be repaired soon.
Step-by-step explanation:
The main verb in the sentence is "to repair", and it is in past participle, since it is preceded by verb to be : will be repaired (verb to be is in Simple Future).
It is passive voice (as opposed to active voice), since the potholes will not fix anything, that is, they will not be the doers of the action, they will rather be the receivers of the action: they will be fixed by someone.
If there is the need to say who the agent- the doer of the action- is, the preposition "by" is used to introduce it. Eg:
The potholes on our street will be repaired by the Department of Transportation soon.
