Why each option

FCoE enables storage and data traffic to share a single Ethernet fabric, reducing hardware costs and consolidating data center I/O.

AAllows Fibre Channel and Ethernet networks to share a single, integrated infrastructure.Correct

FCoE encapsulates Fibre Channel frames within Ethernet frames using the IEEE 802.1Q framework, allowing both FC storage traffic and standard Ethernet data traffic to traverse the same physical switched infrastructure without requiring separate FC fabrics.

BEncapsulates Ethernet frames into Fibre Channel frames, which allows them to run alongside

This reverses the encapsulation direction - FCoE wraps Fibre Channel frames inside Ethernet frames, not Ethernet frames inside Fibre Channel frames.

CIncreases capital costs due to the difficulty to manage.

FCoE reduces capital costs rather than increasing them, because it replaces separate FC HBAs, FC switches, and Ethernet NICs with a single converged network adapter and unified fabric.

DConsolidates I/O traffic in the data center.Correct

By converging Fibre Channel SAN traffic and Ethernet LAN traffic onto a single unified fabric, FCoE eliminates redundant network adapters, switches, and cabling, consolidating all I/O traffic flows within the data center.

EIt allows Ethernet traffic to run over a Fibre Channel infrastructure.

FCoE carries FC storage traffic over an Ethernet infrastructure - Ethernet traffic does not run over a Fibre Channel infrastructure, which is the opposite direction of the technology.
