A Correct answer
Explanation

The Expression transformation in Informatica is a passive transformation that has only input and output ports - no input/output port groups. In contrast, Router has multiple output groups, Lookup has input/output ports and override capability, and Aggregator has input/output groups with aggregate logic. Expression is the only one with simple input/output port structure.
