a. usb to rj-45 dongle
b. expansion card
c. zif connector
d. port replicator
e. docking station

The answer is D and E

Explanation:

There is no much difference between a port replicator and a docking station. These two terms are used interchangeably and both serve the same purpose of connecting portable computers with other devices with little or no effort. The main difference between the two is that a port replicator provides a solution for all laptops through USB while a docking uses a propriety connector to the computer. Users can use a docking station and a port replicator to convert their laptop PCs into desktop computers when at home or in the office.
