Final answer:
The concept inseparable from authority is power. Authority is the power that is accepted because it comes from a legitimate source, and it is intrinsic to the function of leadership, whether through charisma, tradition, or legality.
Step-by-step explanation:
With respect to leadership, the concept that is inseparable from authority is B. Power. Authority is the power to give orders, make decisions, and enforce obedience. It is recognized and followed because it stems from a source that is perceived as legitimate. This can be because of laws, traditions, or the personal qualities of a leader, such as charisma. However, authority inherently involves the ability to exert power. For example, charismatic leaders like Hitler and Jesus Christ possessed personal appeal that commanded follower loyalty and obedience, thus demonstrating their power through authority.
Leaders may have authority from different sources, including tradition, legality, or charisma. Charismatic authority is based on the exceptional personal qualities of a leader, which inspires and draws followers. Rational-legal authority, on the other hand, derives its power from a system of rules and laws, such as a constitution. Both forms still encompass the concept of power as fundamental to authority. People follow and accept the authority of traditional figures, such as kings or tribal chiefs, because of societal customs and their inherent power within the culture.
