Identify the type of validation check that will help prevent input error in the following scenario: A user needs to enter a valid email address (must have an @ symbol).

Question

The scenario asks for a validation check that prevents input errors when a user must enter a valid email address that includes an @ symbol.
Option a: Range check. This type of check is used to ensure a value falls within a specified numeric or ordered range (e.g., 1-100). It is not appropriate for validating email structures.
Option b: Format check. This is the appropriate choice because a format check verifies that the input adheres to a specified pattern or format, such as containing an @ symbol and following a general email structure (e.g., text@domain). It directly addresses the requirement of a valid email format.
Option c: Presence check. A presence check ensures that a field is not left blank, i.e., something is entered. While this helps avoid empty submissions, it does not ensure that the entered value resembles an email address or includes an @ symbol.
Option d: Length check. A length check constrains how many characters the input can have, which can help prevent overly long or short inputs, but it does not verify that the input matches the standard email format or contains an @ symbol.
In summary, to ensure an input is a valid email address with an @ symbol, validating the format of the input is the appropriate mechanism, since it enforces the required structural pattern rather than merely checking range, presence, or length. Therefore, the format check is the suitable validation approach for this scenario.
