Choice A is a synthesis reaction, I believe an anion and cation combine to form a binary compound. Choice B is a double-displace reaction because a precipate was formed. Choice D is, um, idr. .-.  Not a decomp. reaction

Choice C is definitely a decomposition reaction. You start off with a metal carbonate. It decomposes to a metal oxide plus carbon dioxide, which are the products.
