Which of the following could be considered a public relations tool?

Social media platforms are considered a public relations tool because they enable organizations to communicate directly with their target audiences in real-time. They facilitate engagement, allowing organizations to share information, respond to inquiries, and build relationships with stakeholders, including customers, journalists, and the general public. Through social media, companies can enhance their brand image, communicate key messages, and manage their reputation. The interactive nature of social media allows for a two-way dialogue, which is essential in public relations for establishing a rapport with audiences and fostering community engagement.

In contrast, while financial reports provide essential information about an organization's performance and may be used for transparency, they primarily serve a different institutional purpose and are not tools for direct public engagement. Manufacturing equipment is also not a communication tool; it is part of the operational infrastructure of a company. Sales presentations aim to persuade potential customers to purchase products or services but are not primarily focused on the broader public relations goals of reputation management and stakeholder engagement.
