D Correct answer
Explanation

Stage variables in parallel Transformer stages can execute functions once per record for row-level calculations, once per run for initialization, and identify the first row of an input group using @INROWNUM or other techniques. This versatility makes stage variables powerful for complex transformation logic requiring different execution scopes.
