Define 'social media'.

The definition of 'social media' is accurately captured as platforms that enable users to create and share content or engage in social networking. Social media encompasses a variety of websites and applications that foster interactions among individuals and communities. Users can post updates, share photos and videos, interact through comments, and express their opinions, making it a dynamic space for communication and connection.

This definition differentiates social media from other types of online platforms. For instance, websites that provide news and information primarily focus on delivering content rather than facilitating interaction among users. Similarly, applications dedicated to editing photos and videos are tools for content creation rather than platforms for social networking. Lastly, online stores are specifically designed for transactions and e-commerce, which does not align with the core purpose of social media as a space for social interaction and content sharing. Thus, option A stands out as the most fitting description of social media.
