Answer:
Deceptive
Step-by-step explanation:
Since the word hypocritical means acting one way when you mean another, deceptive works in this sentence, since deceptive means something looks one way when it is actually not that way.
An example of hypocrisy is saying bullying is bad and then bullying someone yourself. That's acting one way when you mean another, going back on your word and being deceptive, because everyone thinks you're nice but in fact you are not.
Hopefully that helps :)
