What is required for using OnDemand?

To effectively use OnDemand, a compatible Java JVM-capable browser is essential. This is because OnDemand applications often rely on Java applets or components that necessitate execution within a Java-enabled environment. The use of a browser that supports Java Virtual Machine (JVM) capabilities allows the OnDemand features to function properly, ensuring that the necessary Java scripts and applets can run smoothly.

The compatibility with Java is crucial, as it enables the deployment of dynamic applications that may require Java for loading, executing, or rendering functionalities within the browser. This makes option B the correct choice when considering the requirements for OnDemand usage, emphasizing the importance of a browser that can handle Java applications.

In contrast, while modern browsers with HTML5 support are essential for many web applications, they may not provide the specific Java capabilities necessary for OnDemand. Therefore, relying on just modern HTML5 features without JVM support would be insufficient. Similarly, while a secure EPM (Endpoint Protection Manager) install and specific browser plugins might enhance the overall experience or security, they are not the fundamental requirement needed to utilize OnDemand effectively. Ultimately, the specific need for a Java-capable browser sets option B apart as the correct answer.
