What is an 'influencer' in the realm of social media?

An 'influencer' in social media is defined as a social media user who has the ability to sway or impact the opinions, behaviors, or purchasing decisions of others. Influencers often build their credibility and following on specific topics or niches, which allows them to engage with their audience effectively. Their content often prompts followers to take action, whether that's making a purchase, trying a new brand, or adopting a new trend.

Influencers typically create content that resonates with their audience, and they leverage their relationships and credibility to promote products or ideas. This power to affect others is primarily what distinguishes them from casual users, making option C the most accurate definition of an influencer in this context.

In contrast, the other options do not capture the essence of what an influencer does or represents. A user who primarily consumes content does not participate in a way that impacts others and therefore lacks the influence that characterizes a true influencer. A brand representative may promote a brand but typically has a more formal role tied to a specific company, lacking the organic engagement followers expect from an influencer. Similarly, a special type of follower with privileges does not imply the same level of influence over opinions or behaviors as an influencer possesses.
