Which activity in a Process Model is suitable for displaying a form?

The activity in a Process Model that is suitable for displaying a form is the user input task. This task is specifically designed for scenarios where human interaction is required. It allows users to fill out forms and provide input, making it essential for gathering information or feedback from stakeholders during the workflow.

User input tasks are integral to processes that require decision-making or approvals, as they facilitate direct engagement from users. The forms presented in this task can be customized to collect relevant data, guiding users through the necessary input steps to keep the process moving efficiently.

In contrast, the other task types serve different purposes. A script task is geared towards executing backend logic without user interaction, while a service task automates integrations with external systems or services, also without requiring user input. An end event signifies the termination of the process and does not involve displaying any forms. Thus, the user input task is the appropriate choice for scenarios involving form displays in a process.
