Responsive Web Design: showing collections

I have been tasked with a responsive web design solution and a client had made an unusual and challenging request.

My client is asking me to display a collection of related items. I proposed a couple of solutions, but the client is requesting what I believe to be a conceptually questionable approach albeit doable.

I want to know if I'm wrong.

In terms of responsive web design, which one of the following three illustrations, would you deem is not an ideal solution to present a collection of items.

(Please note, pizza is there for dramatic effect. My project has nothing to do with pizzas, pretend the pizza is a grid if it bothers you.)
