Which sentence from george orwell’s shooting an elephant is the best example of orwell’s intentional use of irony?

“i had almost made up my mind that the whole story was a pack of lies, when we heard yells a little distance away.”

“if he charged, i could shoot; if he took no notice of me, it would be safe to leave him until the mahout came back.”

“they had not shown much interest in the elephant when he was merely ravaging their homes, but it was different now that he was going to be shot.”

“early one morning the sub-inspector at a police station the other end of town rang me up on the phone and said that an elephant was ravaging the bazaar.”
