Why each option
To add a physical interface to an EtherChannel, you must enter the physical interface's configuration mode before specifying its inclusion in a channel group.
The command `interface port-channel 2` configures the logical EtherChannel bundle itself, not the physical member interface being added.
This option is identical to C, but it's a duplicate and not the designated correct answer.
The command `interface fastethernet 1/1` is the essential first step to configure the specific physical interface that will be added to the EtherChannel bundle, where you would then use `channel-group <number> mode <mode>`.
The command `interface port-channel 2` configures the logical EtherChannel bundle itself, not the physical member interface being added.
