Which one of the following does not border Panama?

Panama has land borders only with two countries: Costa Rica to the west and Colombia to the east; these are the only nations sharing frontiers with Panama by land. Geographically Panama is an isthmus bounded by the Caribbean (Atlantic) to the north and the Pacific Ocean to the south, giving it extensive coastlines but only the two land neighbors noted above [1]. Venezuela does not share a land border with Panama; it lies across the Caribbean Sea and is separated from Panama by other maritime space and the territory of Colombia to the east, so it is not a bordering country of Panama. Therefore Venezuela is the option that does not border Panama.
