Why might Ana not see her lead template in the Select Data template step?

The correct answer indicates that Ana did not flag the 'Active' checkbox on her lead template. Templates in many systems often have states that determine their visibility and usability. When the 'Active' checkbox is unchecked, it signifies that the template is not currently available for use, which directly impacts whether Ana can see it when navigating through the Select Data template step.

For a template to be accessible, it generally must be marked as active. This ensures that only templates that are intended for use are displayed to users, thereby reducing clutter and potential confusion in the selection process. Even if a template is created correctly and exists within the system, if it is not marked as active, it won't be shown as an option.

In contrast, factors like forgetting to save the template or creating it in a different environment would typically lead to other kinds of issues, such as the template not being available at all, rather than simply not visible in a selection step. Likewise, not setting the template as public would influence its availability to others rather than affecting Ana’s ability to see it personally if she is still the owner of the template. Therefore, not flagging the 'Active' checkbox is the definitive reason why the template would not appear for her selection.
