Select the option that expresses the following sentence in passive voice.
His brother needed some urgent help at that moment.

Correct option is B

The correct passive voice is (b).
Active Voice: The subject performs the action expressed by the verb.
Passive Voice: The subject receives the action expressed by the verb.
Active voice (past simple): Subject + verb (V2) + object
Passive voice: Object + was/were + past participle + by + subject
Explanation:
“Needed” is in past tense, so passive form will be: “was needed”
Also, “that moment” should not be changed to “this moment” — tense consistency matters.
Example: She needed help → Help was needed by her.
�� Information Booster: Always maintain original time expressions (this/that) in passive construction.
