Select the option that expresses the given sentence in passive voice.
John bought sweets at the store when he visited yesterday.

Correct option is B

The correct passive voice is (b).
Active Voice: When the subject of the sentence performs the action, the sentence is in active voice.
Passive Voice: When the subject of the sentence receives the action, the sentence is in passive voice.
Active voice (past simple): Subject + V2 + object
Passive voice: Object + was/were + V3 + by + subject
Example: She painted a picture → A picture was painted by her.
Hence, "John bought sweets…" becomes "Sweets were bought by John…"
�� Information Booster: Use “was/were + V3” in passive voice of past simple tense.
