C.) Only docking stations have expansion slots

Explanation:

Port Replicators offer the same functionality found in docking stations but are more universal. Port replicators don't require the laptop to be clipped into a docking port, as docking stations do. Instead, the replicator device connects through a simple USB port, commonly found on any laptop made today. A port replicator is similar to a docking station , but does not include expansion slot .
