The 'Lease Time' is the correct answer because it is the setting within a DHCP configuration that specifies the duration for which an IP address is allocated to a client before it needs to be renewed. A shorter lease time can help in environments where devices frequently connect and disconnect from the network, ensuring that IP addresses are returned to the address pool sooner and can be reallocated as needed. Increasing the 'Range' would only broaden the total number of IP addresses available, which is not relevant to how long an IP address is assigned to a device. A 'Reservation' is used to assign a specific IP address to a single device based on its MAC address and is persistent, not temporary. 'Scope Options' are configurations allowing for additional settings on a DHCP server, like DNS servers or default gateway, but does not pertain to the lease duration.
