The correct answer is A. The external facing interface of the FortiGate unit is configured to use DHCP. B. The FortiGate unit has not been registered. C. There is a NAT device between the FortiGate unit and the FortiGuard Distribution Network and no. Possible reasons for FortiGate push updates not being received include improper external interface configuration (like DHCP issues), an unregistered unit, or unconfigured NAT for FortiGuard communication.

Why each option
Possible reasons for FortiGate push updates not being received include improper external interface configuration (like DHCP issues), an unregistered unit, or unconfigured NAT for FortiGuard communication.
While DHCP itself is not a barrier, if the DHCP configuration on the external-facing interface fails to provide proper internet connectivity, such as incorrect DNS servers or a missing default gateway, the FortiGate unit would be unable to reach the FortiGuard Distribution Network to receive updates.
A FortiGate unit must be properly registered with FortiGuard services to receive any updates, whether they are pulled or pushed, as registration links the device to its support contract and entitlements.
If a NAT device sits between the FortiGate and FortiGuard, and port forwarding or a proper outbound NAT rule is not configured to allow the FortiGate to communicate with FortiGuard servers, then updates cannot be received.
FortiGate units operating in Transparent mode can still receive and apply FortiGuard updates, as Transparent mode relates to Layer 2 forwarding of traffic, not its ability to communicate with external services like FortiGuard.
