Which expression can be used to display a status as text from an integer datatype?

The expression that correctly displays a status as text from an integer datatype is based on the use of the displayvalue function. This function maps an integer to a corresponding text representation using two arrays: one for the numeric values and another for the desired text outputs.

In the given expression, initially, an integer value (ri!status) is provided, which is expected to fall within the specified set of integers {1, 2, 3, 4}. For each integer, a corresponding text label is defined in the second array {"Requested", "Reviewed", "Ordered", "Delivered"}. The final parameter of the displayvalue function acts as a default value to return in case the integer does not match any entries in the provided list of integers.

When you pass, for example, the integer 2 to this function, it will successfully map it to "Reviewed". Thus, this expression is designed to convert integer status codes into meaningful text descriptions effectively, ensuring that users will see a clear, contextually appropriate status instead of a mere integer.

In contrast, the other options do not fulfill the task as effectively. For instance, using index would attempt to directly fetch a text value but does not provide a mechanism for handling integers that do not
