Final answer:
Executive leadership refers to a leadership style where the leader has the authority to make decisions without requiring group consensus. It is characterized by a top-down communication pattern, as opposed to democratic or charismatic styles which depend on group input or personal leader appeal.
Step-by-step explanation:
According to Collins, the type of leadership that exists when a leader has the power to simply make decisions is known as C) Executive leadership. Executive leaders have the authority to issue orders and assign tasks, focusing clearly on meeting goals, much like entrepreneurs or corporate executives. This leadership is characterized by a top-down communication pattern wherein the leader decides and directs all actions without requiring consensus from subordinates.
Other types of leadership mentioned by Collins include charismatic leadership, which is based on a leader's personal qualities and ability to inspire followers. Such leaders tend to hold power temporarily and can be as likely tyrannical as they are heroic, exemplified by historical figures like Hitler or Jesus Christ.
It is important to note the distinct differences between executive leadership, characterized by individual decision-making power, and other forms such as democratic or charismatic leadership, which either depend on group consensus or the individual appeal of the leader, respectively.
