B.
The GLBP group number
C.
The type of encapsulation
D.

Explanation:
Each router keeps a unique MAC address for its interface. This MAC address is always
associated with the unique IP address configured on the interface. For the virtual router
address, HSRP defines a special MAC address of the form 0000.0c07.acxx, where xx
represents the HSRP group number as a two-digit hex value. For example, HSRP Group 1
appears as 0000.0c07.ac01, HSRP Group 16 appears as 0000.0c07.ac10.
