The correct answer is letter E
Leadership can be defined as the ability to influence a group to achieve goals. The origin of this influence can be formal, like that given by a high position in the organization. As these positions refer to a certain degree of authority, a person can assume a leadership role only according to the position he holds. Not all leaders are managers and not all executives are leaders. The fact that the organization gives its executives some formal rights does not guarantee their ability to lead effectively. Unsanctioned leadership - one that can influence others, that emerges outside the formal structure of the organization - is usually just as important as formal influence, if not more so. In other words, leaders can appear naturally within a group or by formal indication. In this sense, one of the interpersonal skills whose value is high for organizations is leadership.
