The question is outdated, since R81 Security Zones can be used in NAT rules.
"NAT policy supports Security Zones only for R81 Security Gateways and higher."

A as Sec Zones can be used in the Manual Hide rules

Working with Automatic NAT Rules
You can create Automatic NAT rules for these objects:
Security Gateways
Hosts
Networks
Address Ranges
The answer is A. Security zones will not work in Automatic NAT rules.
Security zones are used to control traffic between different parts of a network. They can be used in firewall policies to control which traffic is allowed or denied. However, they cannot be used in Automatic NAT rules.
Automatic NAT rules are used to automatically translate private IP addresses to public IP addresses when traffic leaves the network. Security zones are not used in Automatic NAT rules because they are not needed. The firewall will automatically translate the IP addresses based on the security zone that the traffic is coming from or going to.
Correct answer is A.
A. There is no option for Automatic NAT in Zones configuration. Zone object is read-only.
B. You can select zone when configuraing manual NAT! Just type InternalZone and you will be able to select it and add to NAT rule
C. Same as with point B- you can add zone to policy
D. Security zones are actually used in network topologies - this is where you define them
Correct Answer is A. Security zones will not work in Automatic NAT rules
Tested this in Demo mode for R81.10. Manual NAT rules can be created using Zone objects.
Automatic NAT rules cannot be created through Zone objects as Zone objects doesn't even have any NAT options within.
Answer A, Tested in LAB
