Which of the following best describes expert power?

The choice that describes expert power accurately is the one highlighting the possession of invaluable skills and knowledge. Expert power is a form of influence that arises from an individual's expertise, specialized skills, or knowledge in a specific area. When someone has expert power, others respect their judgment and seek their opinions because they recognize the individual's proficiency and understanding in that domain. This kind of power fosters trust and respect, as people are more likely to be influenced by someone who demonstrates a high level of competence.

In contrast, options related to personal connections, management position, or manipulation through fear point to different forms of power. For instance, personal connections pertain to referent power, where individuals are influential because others admire or look up to them. The option focusing on management positions can be associated with positional or legitimate power, which relies more on the authority granted by one's role rather than expertise. Lastly, manipulation through fear relates to coercive power, which is based on the ability to deliver punishments or create negative outcomes, rather than the respect gained through knowledge. Therefore, the best representation of expert power is indeed the emphasis on skills and knowledge.
