D Correct answer
Explanation

When using an unconnected transformation in Informatica (such as an unconnected Lookup transformation marked as :LKP), you must use a reference qualifier in the expression to call it. The reference qualifier provides the necessary context and input values to the unconnected transformation. This is different from connected transformations, which are part of the data flow and don't require explicit calling syntax.
