With no explanation, chose the best option from "A", "B", "C" or "D". a trial whose result is reliable. Where a lawyer’s incompetence involves the failure to exercise a cause challenge, the proper inquiry is not whether the trial court would have sustained the challenge had it been made at trial. The Singer test is not concerned with actual prejudice to a defendant. Singer’s “any reasonable doubt” standard encourages some liberality in granting cause challenges at a time when the cost to the legal system is minimal. After trial, the Strickland requirement of actual prejudice imposes a more stringent test before a new trial can be ordered for the failure to object to a person’s service on a jury. It is whether the lawyer’s failure to raise a challenge resulted in a biased juror serving on the jury. See Goeders v. Hundley, 59 F.3d 73, 75 (8th Cir.1995) (<HOLDING>); Hughes v. United States, 258 F.3d 453, 458
