Select the correct active form of the given sentence.
I am trusted by all my friends.

Correct option is C

The correct active form of the sentence is "All my friends trust me."
· Active Voice- Active voice is a grammatical structure in which the subject of the sentence performs the action expressed by the verb.
· Passive Voice- Passive voice refers to a grammatical construction where the subject of a sentence undergoes an action rather than performing it. In passive voice sentences, the emphasis is on the recipient or object of the action.
Conversion rule:
Subject + verb + object -> <- Object + auxiliary verb (is, am, are) + past participle + by + subject.
This maintains the meaning of trust being placed in the speaker by the friends in the active voice.
