The lower the number, the higher the priority. So if active is higher priority, therefore assigned 100 , then the only one that will be second priority will be with number larger than 100 so Only 255 is applicable. Therefore D is the correct answer.

The firewalls in an Active-Passive HA pair can be assigned a device priority value to indicate a preference for which firewall should assume the active role. If you need to use a specific firewall in the HA pair for actively securing traffic, you must enable the preemptive behavior on both the firewalls and assign a device priority value for each firewall. The firewall with the lower numerical value, and therefore higher priority, is designated as active. The other firewall is the passive firewall.

The firewall you plan to make active must have a lower numerical value than its peer. So, if Peer A is to function as the active firewall, keep the default value of 100 and increment the value on PeerB.
