What are the steps a DHCP client goes through when requesting an IP address? Make sure they are in the correct order

A) DHCPDISCOVER, DHCPOFFER, DHCPREQUEST, DHCPACK
B) DHCPDISCOVER, DHCPREQUEST, DHCPOFFER, DHCPACK
C) DHCPOFFER, DHCPDISCOVER, DHCPREQUEST, DHCPACK
D) DHCPACK, DHCPDISCOVER, DHCPREQUEST, DHCPOFFER

A
Explanation:
1. When a DHCP client initially boots, it has no IP address, default gateway, or other such configuration information. Therefore, the way a DHCP client initially communicates is by sending a broadcast message (that is, a DHCPDISCOVER message to a destination address of 255.255.255.255 ) in an attempt to discover a DHCP server.
2. When a DHCP server receives a DHCPDISCOVER message, it can respond with a unicast DHCPOFFER message. Because the DHCPDISCOVER message is sent as a broadcast, more than one DHCP server might respond to this discover request. However, the client typically selects the server that sent the first DHCPOFFER response received by the client.
3. The DHCP client communicates with this selected server by sending a unicast DHCPREQUEST message asking the DHCP server to provide IP configuration parameters.
4. The DHCP server responds to the client with a unicast DHCPACK message. This DHCPACK message contains a collection of IP configuration parameters.
