You work as a network technician at. You study the network topology and the other exhibits carefully. Consider the distribution switches 1 and 2. 1 is the primary device for Vlan 101， 102， 105. 2 is the primary device for Vlan 103 and 104 
Note： Please refer to the #2 scenario. 
During routine maintenance， it became necessary to shutdown G1/0/1 on1 and2. 
All other interface were up. During this time，1 became the active device for Vlan104’s HSRP group. As related to Vlan104’s HSRP group. 
What can be done to make the group function properly ？（）

A . On 1， disable preempt
B . On 2， decrease the priority value to a value less than 150
C . On 1， increase the decrement value in the track command to a value greater than 6
D . On 1， disable track command.
