Which one of the following is TRUE?

The answer is C because inline layer can be defined as a rule action in a policy layer. Inline layer is a sub-policy that contains additional rules that are applied only if the parent rule matches. Ordered layer is a policy layer that contains rules that are applied in order, from top to bottom. One policy can be either inline or ordered, but not both. Pre-R80 Gateways do support ordered layers, but not inline layers5 References: Check Point R81 Policy Layers and Sub-Policies, [Check Point R81 Security Gateway Administration Guide]
