Tick (✓) one box to show which check is used for verification when data is input. A length check □ B range check □ C type check □ D visual check □

Choice D is correct because: Verification is the process of checking that data has been copied accurately and matches the original source document during data entry. A visual check (or screen check) involves the user reading and comparing the data entered on the screen against the original paper or source document to detect any transcription errors. Since a visual check directly confirms whether the entered data accurately reflects the source data, it is a recognized method of verification (along with double entry). Choice A is incorrect because: A length check is a method of validation, not verification. It is an automated check performed by software to ensure that the data entered contains a specific number of characters (or is within an acceptable minimum/maximum number of characters), rather than verifying if it matches the source. Choice B is incorrect because: A range check is a method of validation, not verification. It checks whether a numerical input falls within predefined upper and lower boundaries (for example, a month value must be between 1 and 12). It does not confirm if the entered number is the exact value intended from the source document. Choice C is incorrect because: A type check is also a method of validation, not verification. It verifies that the entered data is of the correct data type (such as ensuring that an age field contains only integers and no alphabetic characters), but it does not check if the entered data matches the original source.
