    A. GigabitEthernet1/0/1 and GigabitEthernet1/0/2 can be added to the same LAG without changing the current configurations.
    B. After link aggregation is configured on SWA and SWB, if MSTP is enabled on them, GigabitEthernet1/0/1 and GigabitEthernet1/0/2 enter the Forwarding state in MSTP.
    C. GigabitEthernet1/0/1 and GigabitEthernet/0/2 can be added to the same LAG only after the configuration of GigabitEthernet/0/2 is changed to be the same as that of GigabitEthernet1/0/1.
    D. GigabitEthernet1/0/1 and GigabitEthernet/0/2 cannot be added to the same LAG because the allowed VLANs are different.
