It does not create a pseudowire class named cisco. It is just referencing the class to use that should be created separately. Output from an ASR-920 (IOS-XE):
Router(config-if)#xconnect 1.1.1.1 1 pw-class ?
WORD Pseudowire-class name
Router(config-if)#xconnect 1.1.1.1 1 pw-class cisco
Please make sure pw-class cisco is configured
Please make sure pw-class cisco is configured and valid [Unknown pseudo-wire class name]
It enables AToM on interface. It does not CREATE a pseudowire class but USES the pseudowire class Cisco (we don't see that in the configuration but it has to be created already)
B from what the configuration guide tells us:
https://www.cisco.com/c/en/us/td/docs/optical/cpt/r9_5/configuration/guide/cpt95_configuration/cpt93_configuration_chapter_0111.html
"Example: Create a Pseudowire
The following example creates a static pseudowire using Cisco IOS commands:
Router> enable
Router# configure terminal
Router(config)# interface TenGigabitEthernet4/1
Router(config-if)# xconnect 10.131.191.251 100 encapsulation mpls pw-class class1"
Sorry, I think it must be C.
Cisco and their stupid word games!
B must be wrong because the configuration does NOT actually CREATE the pw-class Cisco.
From Cisco:
Step1: Create pseudowire class:
PE2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
PE2(config)#pseudowire-class TEST
PE2(config-pw-class)# encapsulation mpls
PE2(config-pw-class)#exit
Step2: Configure Cross connect on point to point interface
PE2(config-if)#int e1/0
PE2(config-if)# xconnect 1.1.1.1 101 encapsulation mpls pw-class TEST
PE2(config-if)#exit
C is correct - it enables AToM on interface gigabitethernet1/0
I don't know if C is correct? Could be the B?

I think its not B, because the command in B mean: create xconnect with neighbor x.x.x.x and vcid 12 using an encapsulation mentioned in a PW class named cisco. So its not creating, its referring.
Specifies the tunneling method used to encapsulate data in the pseudowire. AToM uses MPLS as the tunneling method.
Router(config-if)# xconnect
peer-router-id vcid
encapsulation mpls
