The displayvalue() function searches for the value parameter (1) within the array parameter ({0, 1, 2}). It finds a match at the second position (index 1). The function then returns the item from the replacementarray ({"Low", "Medium", "High"}) at the same index. The value at index 1 in the replacement array is "Medium". The default value "Unknown" is only returned if the initial value is not found in the search array.

A. Low: "Low" is at index 0 of the replacement array. This would be returned if the value being searched for was 0, not 1.

C. High: "High" is at index 2 of the replacement array. This would be returned if the value being searched for was 2, not 1.

1. Appian Documentation: displayvalue() Function. This official documentation page details the function's syntax: displayvalue(value, inarray, outarray, default). It explicitly states, "Returns an element from outarray that is at the same index as the first occurrence of value in inarray." This directly supports the logic that finding 1 at index 1 in the input array results in returning the element at index 1 from the output array.

Section: Syntax and Examples. The provided examples, such as displayvalue(2, {1, 2, 3}, {"a", "b", "c"}, "d") returning "b", confirm this behavior.
