With no explanation, chose the best option from "A", "B", "C" or "D". total offense level was calculated to be 45, but because U.S.S.G. § 5A n. 2 stated that an offense level of more than 43 was to be treated as an offense level of 43, Oliver’s total offense level was set at 43. Based on a total offense level of 43, and a criminal history category of III, the guideline range was life imprisonment. Even with a reduction of Oliver’s base offense level to 38, with the enhancements applied at sentencing in 1993, Oliver’s offense level would be 43. With an offense level of 43, and a criminal history category of III, Oliver’s sentencing range remains life imprisonment. Se -, 129 S.Ct. 965, 173 L.Ed.2d 156 (2009), and cert. denied, — U.S. -, 129 S.Ct. 1601, 173 L.Ed.2d 689 (2009); United States v. Walker, 301 Fed.Appx. 844 (11th Cir.2008) (unpublished opinion) (<HOLDING>). Accordingly, we affirm.

A: holding that the district court lacked authority under  3582c2 to grant a sentencing reduction to defendants who were career offenders sentenced under ussg  4b11 because amendment 706 would not ultimately affect their guideline ranges
B: holding that the district court lacked authority under  3582c2 to grant a sentencing reduction to a defendant who was held accountable for more than 45 kilograms of crack cocaine
C: holding that the recent amendment to the crack cocaine guidelines does not qualify defendant for a sentencing reduction under  3582c2 because defendant was originally sentenced pursuant to the guideline range for career offenders
D: holding that district court did not err in determining that cocaine base was crack cocaine based on chemical analysis identifying cocaine base together with competent lay testimony bridging the evidentiary gap between cocaine base and crack cocaine and refusing to require showing of smokeability ie water solubility or melting point for purposes of establishing crack cocaine under the guidelines since smokeability distinguishes cocaine base from powder cocaine not from crack
