If you want to configure link aggregation to aggregate these two links, if the configuration on SWB is correct, which of the following you can know from the above information?

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-GigabitEthernet1/0/1] gvrp

[SWA-GigabitEthernet1/0/1] port link-type trunk

[SWA-GigabitEthernet1/0/1] port trunk permit vlan 1 10

[SWA] interface GigabitEthernet 1/0/2

[SWA-GigabitEthernet1/0/2] port link-type trunk

[SWA-GigabitEthernet1/0/2] port trunk permit vlan 1 10

If you want to configure link aggregation to aggregate these two links, if the configuration on SWB is correct, which of the following you can know from the above information?
A . Only when all VLANs are allowed to pass through GigabitEthernet1/0/2 and Gigabit1/0/1, can the two 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 . After link aggregation is configured on SWA and SWB, if both SWA and SWB enable MSTP on the aggregation port, one of GigabitEthe1/0/1 and GigabitEthe1/0/2 will be blocked.
D . After link aggregation is configured on SWA and SWB, if both SWA and SWB enable MSTP on the aggregation ports, GigabitEthernet1/0/1 and GigabitEthe1/0/2 can participate in forwarding.
