Answer:
C.
Step-by-step explanation:
Well in this world we already have vending machines in a cafeteria, A would be out of the question and it's not to inform, its for your desires. Telling someone's most embarrassing moments it more of like a friend gathering type discussion, B is out because you are not informing anything its more for entertainment. Telling people to watch a new superhero movie is not informative its more like advertising, D is out as well because thats not something to inform people about.
C, is the most reasonable discussion to have to people. Talking about the safety procedure that they are taking in a woodworking class is important. People could get hurt in that class and there are multiple safety precautions you need to take why in that class. C would be a smart choice and I used to be in a woodworking class as well.
Hope this helps!!
