The intrinsic function Fn::ImportValue returns the value of an output exported by another stack. You typically use this function to create cross-stack references.

B. When referencing resources from another stack, the ImportValue function should be used. If the developer didn't use this, it would cause a failure when trying to reference the subnets. D. For a resource to be imported by another stack, it needs to be exported in the Outputs section of the original stack. If the network team didn't export the subnets, they can't be imported by the developer's stack.
