A and C
I like A and C as well.
My vote is A. I would help him locate the bull and strike up a conversation. He might have had no idea you were there and was just going after what he thought was multiple bulls. If you get the feeling he moved in on purpose, you still help and then go on with your hunt but you never know, he might be willing to help you call a bull in and a long term hunting buddy might be established. Life is too short to lose sleep and get all worked up over something like this. Plenty of elk on the mountain, especially from the sounds of this scenario.
Wow, you guys are all alot nicer than I am!
E. It may have been a mistake on his part, maybe not. Either way it was legal. I'd give him one of these and a REALLY?!?!?! And walk off to go find another elk.
