Why each option

When a single user experiences slow network speeds after an infrastructure upgrade, and other similar users are unaffected, the technician should first replace the patch cable to rule out a simple physical layer issue. This is the simplest and most common point of failure for isolated network problems.

AUpdate Internet bandwidth speed.

Updating Internet bandwidth speed would affect all users and is not a troubleshooting step for an isolated user issue; the problem is likely localized, not a global bandwidth bottleneck.

BUpdate the BIOS firmware.

Updating the BIOS firmware is a complex and potentially risky procedure that is unlikely to be the cause of a sudden, isolated network speed issue and should not be the first troubleshooting step.

CReplace the motherboard.

Replacing the motherboard is a drastic and expensive step, only considered after ruling out simpler causes and identifying a hardware failure, which is not indicated here.

DReplace the patch cable.Correct

A patch cable is a common point of failure for network connectivity issues, and it is inexpensive and easy to replace. Since only one user is affected and the infrastructure was upgraded, replacing the patch cable is the quickest and most logical first step to rule out a physical layer problem specific to that user's connection.
