Q: When all requirements for a form pattern have been satisfied, what must be done before you can build and preview the form in a browser window?

Answer: C

Explanation:

A. The forms pattern report is a .csv file that lists all the forms in the system. It is not a necessary step before previewing a form.
B. The form statistics add-in gives an overview of the controls and pattern coverage on a specific form. It is not a necessary step before previewing a form.
C. You must first set the form you want to preview as the startup object for the project by right clicking the form in the Solution Explorer window and selecting that option.
D. A rebuild of the form will force the elements in a project to be rebuilt and compiled. It will not run the form unless the form was already set as the startup object.
