and his familial obligations did not warrant a downward variance from the advisory Guidelines range. See United States v. Dieken, 432 F.3d 906, 909 (8th Cir.2006) (rejecting defendant’s assertion the district court failed to consider adequately his personal history and troubled family life, holding sentence was reasonable as court considered each section 3553(a) factor and determined defendant’s claims did not “necessitate[;] deviation from the suggested guidelines sentence”); United States v. Fernandez, 443 F.3d 19, 34 (2d Cir.2006) (concluding although the sentencing court had the power to reduce the sentence under section 3553(a) based on defendant’s cooperation, “the court was not obliged to provide any such benefit”); United States v. Laufle, 433 F.3d 981, 988 (7th Cir.2006) ; United States v. Mares, 441 F.3d 1152, 1161

What is the most suitable continuation to the opinion? Your options are:
A. holding that plain error review is used for unpreserved challenges to the method by which the district court arrived at a sentence including arguments that the sentencing court failed to explain adequately the sentence imposed under the statutory factors in  3553a
B. holding that a district court is entitled to give more weight to the seriousness of the offense than to other factors
C. holding that where the plea agreement required the government to inform the sentencing court of all defendants cooperation the issue  is not whether the prosecutor enthusiastically disclosed his cooperation but whether the prosecutor disclosed all cooperation
D. holding although different sentencing court may have given more weight to defendants cooperation disagreement with the courts assessment does not warrant reversal since our task is confined to determining whether the district court considered the appropriate range of factors and arrived at a reasonable sentence
E. holding that judgment calls on the weight to be given various relevant factors are for the sentencing court not for this court
