Which configuration supports the requirements?

A network administrator wants to configure a timing protocol with these requirements:

– Hardware time stamping to achieve sub microsecond synchronization.

– Master IP address: 192.168.1.100.

– Use interface Ethernet 1/1/1 to enable timing protocol.

Which configuration supports the requirements?
A . OS10(config)# ptp clock boundary
OS10(config)# ptp domain 1
OS10(config)# ptp system time enable
OS10(config-if-eth1/1/1)# ptp enable
OS10(config-if-eth1/1/1)# ptp role slave
OS10(config-if-eth1/1/1)# ptp transport ipv4 unicast slave
OS10(config-if-eth1/1/1-ptp-ipv4-slave)# master 192.168.1.100
B . OS10(config-if-eth1/1/1)# ntp authenticate
OS10(config-if-eth1/1/1)# ntp trusted-key 345
OS10(config-if-eth1/1/1)# ntp authentication-key 345 md5 0 5A60910FED211F02
OS10(config-if-eth1/1/1)# ntp server 192.168.1.100 key 345
OS10(config-if-eth1/1/1)# ntp master 7
C . OS10(config)# ntp authenticate
OS10(config)# ntp trusted-key 345
OS10(co345 md5 0 5A60910FED211F02
OS10(config)# ntp server 192.168.1.100 key 345
OS10(config-if-eth1/1/1)# nfig)# ntp authentication-key ntp master 7
D . OS10(config)# ptp clock boundary
OS10(config)# ptp domain 1
OS10(config)# ptp system time enable
OS10(config)# ptp enable
OS10(config)# ptp role master
OS10(config)# ptp transport ipv4 unicast slave
OS10(config-if-eth1/1/1)# master 192.168.1.100
