With no explanation, chose the best option from "A", "B", "C" or "D". burden of proof to the defendant, United States v. Murrieta-Bejarano, 552 F.2d 1323, 1325 (9th Cir.1977). In this case, the district court instructed the jury that deliberate ignorance would come into play if Stone “believed a false and fraudulent claim was being made ... and consciously tried to avoid” actual knowledge.

The second rationale offered by the contrary

A: holding that the trial court erred by giving a misleading instruction
B: holding that a properly worded deliberate ignorance instruction obviates the harmful effects of the erroneous giving of such an instruction
C: holding that unless an erroneous instruction was unlikely to have changed the result of the trial a reviewing court cannot say that giving the instruction was harmless error
D: holding that a party waived an allegation that an instruction was erroneous where the party failed to object at trial to the instruction on those grounds
B.
