What options should be considered by the administrator to ensure required fields must be completed during account creation?

To ensure that required fields must be completed during account creation, verifying that field-level security is not set to "Read Only" is essential. When a field is set to "Read Only", users will not be able to enter any data into that field during the account creation process. As a result, even if the field is marked as required on the page layout, it would not function as intended because users would be unable to provide input. By ensuring that the field-level security allows for editing, the requirement for users to fill in the field can be effectively enforced.

Additionally, while other options may impact user permissions or visibility, they do not directly address the issue of making a field required during the account creation process. Thus, focusing on field-level security is the most pertinent action to ensure compliance with required field completion.
