Which of the Following Is NOT Stated to Be a Problem

Which of the following is NOT stated to be a problem for top-down models of ethical reasoning in Beauchamp and Childress's discussion?

A) To make moral judgments in particular cases, norms must generally be specified and balanced, not simply applied.
B) The top-down model relies too heavily on its likeness to reasoning used in other fields, such as mathematics.
C) When presented with a case, ethical thinkers must select pertinent facts and rules, and selecting the right set of facts and rules is not reducible to a deductive form of judgment.
D) A top-down model creates a potentially infinite regress of justification because every level of appeal to a precept requires a further level to justify that precept.
