Options

ADocking stations provide power to the laptop
BPort replicators plug into a special connector
CDocking stations plug into a USB connection
DPort replicators enable better video sharing

Explanation

The key distinction between a docking station and a port replicator is that a docking station provides AC power to the laptop, eliminating the need for a separate power adapter. Docking stations typically also offer additional expansion capabilities (extra PCIe slots, storage bays, etc.). A port replicator simply duplicates the laptop's existing ports (USB, video, audio) for convenience but does not supply power to the laptop. Neither device exclusively uses USB connections (C), and port replicators do not inherently provide better video sharing (D).
