How can users share dashboards in Oracle Analytics?

Users can share dashboards in Oracle Analytics in several efficient ways, making option B the correct choice. This option highlights the flexibility and accessibility provided by Oracle Analytics for sharing insights and visualizations.

By using direct links, users can easily allow others to access dashboards without needing to send files or printed copies, which can be cumbersome and less interactive. Emailing dashboards to colleagues promotes collaboration and ensures that stakeholders receive timely updates. Additionally, publishing to the analytics community not only shares dashboards widely but also fosters an environment of collective analysis and feedback, allowing users to learn from one another.

The other methods mentioned are restrictive and do not leverage the collaborative and real-time capabilities of modern analytics tools. Options suggest limitations that don't reflect the sharing capabilities typically enabled by tools like Oracle Analytics, which is designed to enhance user experience and data accessibility.
