You have been given an assignment in which you must describe a life-changing experience. Your teacher has stipulated that the entire essay must be written in active voice. Which of these choices would have to be left out or revised for this assignment?

A) I still recall the day I learned to ride a bike.
B) The sun shone brightly as I set out on my quest, determined to learn the proper balance.
C) My friends hailed me with a hearty greeting when they saw me riding my bike all by myself!
D) It was, without a doubt, the best day of my life.

all of these sentences are in the active voice.

C is the only one I would see maybe leading to some passive voice later on.

oobleck is right. There are no passive sentences in your post.
