The correct answer is Technology infrastructure architecture baseline.

The Technology infrastructure architecture baseline documents the current configuration and topology of the organization's infrastructure. It records physical and virtual devices such as servers, storage, network equipment, hypervisors, firmware and platform versions, and network topologies so that administrators have a point in time reference for change control, capacity planning and operational management.

This baseline is the proper source for device level settings and infrastructure standards and it is used when planning upgrades, migrations and configuration management activities. It captures low level implementation details that other architecture baselines do not.

Data architecture baseline is focused on data models, schemas and data flows and it does not specify device configurations. That is why it is not correct for documenting physical or virtual device settings.

Security controls baseline defines the set of security controls and their implementation or compliance status. It concentrates on control requirements and effectiveness rather than detailed hardware and virtualization configurations.

Information systems architecture baseline describes applications, services and system interactions and it may note where systems run. It typically does not include the detailed device configurations and infrastructure topology that the technology infrastructure baseline captures.
