单项选择题During routine maintenance， G1 0 1 on DS1 was shutdown. All other interface were up. DS2 became the active HSRP device for Vlan101 as desired. However， after G1 0 1 on DS1 was reactivated. DS1 did not become the active HSRP device as desired.  What need to be done to make the group for Vlan101 function properly ？ （）

A. Enable preempt on DS1’s Vlan101 HSRP group
B. Disable preempt on DS1’s Vlan101 HSRP group
C. Decrease DS1’s priority value for Vlan101 HSRP group to a value that is less than priority value configured on DS2’s HSRP group for Vlan101
D. Decrease the decrement in the track command for DS1’s Vlan 101 HSRP group to a value less than the value in the track command for DS2’s Vlan 101 HSRP group.
