What is perceived to be a desired ethical value and is seen as an end-goal developed by methodological rigor?

A) objectivity
B) truth
C) competence
D) cost

Perceiving truth as a desired ethical value is essential to the development of sound ethical principles and practices. Methodological rigor is required to ensure that the truth is uncovered rather than subjective biases or opinions. Objectivity and competence are also important ethical values, but they are not the end-goal of methodological rigor. Cost is not an ethical value but rather a factor to be considered in decision-making related to ethics.
