Answer:
It's the last one.
Explanation:
It's deceived. If you look at the sentence, it says he has been something. Therefore it is in past tense. And any of the other answers would not make sense if you look at it, except for "deceiving", but he hung his head in sorrow, making it seem like he was upset.
The other two answers would not work at all, unless you change the tense.
"When he learned he had been deceive,"
That makes no sense!
"When he learned he had been deception,"
Neither does that answer.
So, the answer is "Deceived."
