The little boy called up his best friend on his birthday.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is His best friend was called up by the little boy on his birthday i.e. option 2.
In the passive voice construction:
- "His best friend" becomes the subject.
- "was called up" is the passive form of "called up."
- "by the little boy" indicates the doer of the action in the original sentence and is introduced with "by" in the passive construction.
