I like the fact that the plastic container of tablets contains more, and also that it's a plastic container. That's what I'm more familiar with in terms of vitamin supplement packaging, so I feel more comfortable with Option B here. I'm not sure what the addition of Copper means for this product, but I'd still go with Option B.
What they didn't likeI was just less comfortable buying this Zinc supplement in a box. I like the plastic pill bottles; that's what I'm used to and prefer. Also, you get more tablets with the other option, and I like getting more so I don't have to buy replacement bottles so often.
