Let's analyze this shape combination problem. Amanda has specific shapes available: two cones, one long rectangular prism, two cubes, and two cylinders. We need to determine which of the given options she can actually construct using only these available shapes.
Let's examine Option A. This structure requires one long rectangular prism as the base, three cubes placed side by side on top, and one cylinder on the rightmost cube. However, we only have two cubes available, but Option A needs three cubes. Therefore, we cannot construct Option A with the given shapes.
