With no explanation, chose the best option from "A", "B", "C" or "D". Coker’s attempt to conflate the two, “upward adjustments” (also known as “sentence enhancements”) and “upward departures” are two different things. The Guidelines Manual explains that “adjustments” are applied first to calculate a defendant’s guideline range, U.S.S.G. § 1B1.1(c), (e), while “departures” are given only at the end of the sentencing process and after all adjustments have been applied. Id. at § 1B1.1(i). An “upward departure” is “a sentence greater than a sentence that could be imposed under the applicable guidelines range,” id. at § 1B1. that a defendant who waives the right to challenge her sentence unless the court “departs upward” cannot challenge the district court’s calculation of sentence enhancements. United States v. Fogg, 409 F.3d 1022, 1025 (8th Cir.2005) (<HOLDING>); United States v. Flint, 156 Fed.Appx. 252

A: holding that district courts error was not harmless because the court relied on an improper factor in imposing an upward departure
B: holding harmless any error in departing upward under ussg  4a13 where district court alternatively imposed reasonable sentence as an upward variance
C: holding appeal of enhancement under ussg  3allb waived because it was an adjustment rather than an upward departure 
D: holding that waiver of right to appeal sentence unless its was an upward departure barred appeal of sentence within guidelines range
