Which of the following is one of the traits shared by most successful leaders?

A) integrity
B) external locus of control
C) perceptual predetermination
D) high need for power

Most successful leaders possess integrity as a key trait, which involves honesty, strong moral principles, and consistency in behavior. This builds trust and credibility with followers, enabling leaders to effectively communicate their vision and goals and inspire others to follow them. External locus of control, perceptual predetermination, and high need for power are not necessarily traits shared by successful leaders, and may even hinder their ability to lead effectively.
