Which option helps determine the cause of a performance issue if an application takes more than 10 seconds to load a form?

The Performance Dashboard is particularly useful for diagnosing and identifying the cause of performance issues in an application. It provides a comprehensive view of the application's performance metrics, allowing you to visualize and analyze data regarding various aspects, such as response times, database queries, and service times.

When an application takes an excessive amount of time, such as more than 10 seconds to load a form, the Performance Dashboard can pinpoint the specific areas contributing to slow performance. It can highlight which activities are taking longer than expected and whether certain resources are being overutilized. This level of insight helps developers and system architects to quickly identify bottlenecks, enabling them to make informed decisions to optimize the application's performance.

In contrast, other options may have specific uses in performance monitoring or debugging but do not provide the holistic view that the Performance Dashboard does, making it the most appropriate choice for understanding performance-related issues.
