Why each option
ExpressCard 54 is the laptop expansion slot technology most likely used to add a gigabit Ethernet NIC to a laptop, as it provides sufficient bandwidth and physical compatibility.
ExpressCard 54 is a laptop expansion slot standard that uses either USB 2.0 or PCIe x1 signaling internally and provides enough throughput for gigabit Ethernet. It is the purpose-built mechanism for adding expansion cards such as NICs directly to a laptop, making it the most appropriate choice for a hardware adapter installation.
USB 2.0 has a theoretical max of 480 Mbps, which is insufficient to deliver true gigabit (1000 Mbps) throughput for a dedicated NIC.
PCIe slots are found on desktop motherboards, not laptops, making this an incorrect choice for a laptop installation.
A port replicator extends existing ports but does not add new internal hardware adapters like a dedicated gigabit NIC.
