Passive Form: [Thing receiving action] + [be] + [past participle of verb] + [by] + [thing doing action] In passive sentences, the thing receiving the action is the subject of the sentence and the thing doing the action is optionally included near the end of the sentence. You can use the passive form if you think that the thing receiving the action is more important or should be emphasized. You can also use the passive form if you do not know who is doing the action or if you do not want to mention who is doing the action. *Simple Past : Active :Sam repaired the car. Passive :The car was repaired by Sam. #1) I was made clear by you.Thanks!( correct)

"You made me clear" is a meaningless sentence. What are you trying to say? Now I understand. You helped me understand. You helped me get clear on this.
