問題文

A user can open an account record and read every field, but the Edit button is not available to her. She does have edit access to the Account object. What explains this?

選択肢

1. Field-level security is set to read only for all of the fields on the account, which removes the Edit button from the record page while still allowing her to read the values.
2. She has read access to that particular record through the sharing model but not edit access.
3. The page layout does not include the Edit button, which is chosen separately for each layout in use.
4. A validation rule prevents her from saving, so the button is withheld until the record satisfies the rule.
