With no explanation, chose the best option from "A", "B", "C" or "D". of lowering his sentencing range, and § 3582(c)(2) does not afford him relief. Moore, 541 F.3d at 1327-28. Smith’s argument that we are not bound by Moore because Moore violates Booker is unavailing as we are bound to follow prior binding precedent “unless and until it is overruled by this [C]ourt en banc or by the Supreme Court.” United States v. Vega-Castillo, 540 F.3d 1235, 1236 (11th Cir.2008) (quotations omitted), cert. denied, — U.S.-, 129 S.Ct. 2825, 174 L.Ed.2d 556 (2009). There is no dispute that Moore has not been overruled by either this Court sitting en banc or the Supreme Court, and we are therefore bound to follow it. See id. Finally, Smith’s argument that Moreno is inapplicable here also fails, given our holding in United States v. Melvin, 556 F.3d 1190, 1192 (11th Cir.) (<HOLDING>), cert. denied, - U.S. -, 129 S.Ct. 2382, 173
