Why each option
HSRP version 1 uses a specific virtual MAC address format where the last octet is the hexadecimal representation of the HSRP group number.
This MAC address does not conform to the standard HSRP virtual MAC address format.
This MAC address format (`00:05:5e`) is typically associated with VRRP, not HSRP.
This MAC address format (`00:05:0c`) is not the standard HSRP virtual MAC address prefix.
The default virtual MAC address for HSRP Version 1 groups follows the format `0000.0C07.ACxx`, where `xx` represents the HSRP group number in hexadecimal. For HSRP group 14, the hexadecimal value is `0E`, resulting in the virtual MAC address `0000.0C07.AC0E`.
