One Problem with the Competency (Trait)perspective of Leadership Is That

One problem with the competency (trait) perspective of leadership is that:

A) research doesn't find any evidence that effective leaders have specific competencies.
B) competencies reflect the leader's performance rather than potential.
C) most leadership competencies are too specific, leaving no opportunity to interpret their meaning broadly.
D) it implies a universal rather than contingency approach to leadership.
E) researchers haven't yet considered physical appearance in the list of possible leadership traits.
