From the above, we can know which of the following?

Switches SWA and SWB are connected together through two optical fiber Gigabit Ethernet links, and the following interface configuration is available on switch SWA:

[SWA] interface GigabitEthernet 1/0/1

[SWA-GigabitEthernet 1/0/1] gvrp

[SWA-GigabitEthernet 1/0/1] port link-type trunk

[SWA-GigabitEthernet 1/0/1] port trunk permit vlan 1 10

[SWA] interface GigabitEthernet 1/0/2

[SWA-GigabitEthernet 1/0/2] port link-type trunk

[SWA-GigabitEthernet 1/0/2] port trunk permit vlan 1 10

From the above, we can know which of the following?
A . GigabitEthernet1/0/1 and GigabitEthe1/0/2 cannot be added to the same aggregation group
B . Only when the configuration of GigabitEthe1/0/2 is changed to be consistent with that of GigabitEthe1/0/1, can the two be added to the same aggregation group.
C . If MSTP is enabled on the SWA4 switch, one of GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 will be blocked.
D . If the SWA switch has MSTP enabled, GigabitEthe1/0/1 and GigabitEthe1/0/2 can participate in forwarding
