Identify the correct passive voice version of the sentence. The guard stopped the visitors at the entrance.

Correct option is B

· Active Voice: Denotes that the noun or pronoun that acts as the subject in the sentence is the doer of the action. In other words, the subject performs the action or acts upon the verb.
· Passive Voice: Represents that the subject is one acted upon by the action or verb in the sentence. It can also be said that the passive voice indicates that the subject in the sentence is no longer active but passive.
· The sentence is an example of active voice with simple past tense having the form:
· Sub + V2 + obj + at + place.
· When it is converted into passive voice, the following rule is followed:
· Obj + was/were + V3 + by + sub + at + place.
· Thus, the correct transformation of the given sentence to its passive form is option (b) "The visitors were stopped by the guard at the entrance."
