In TOGAF, each ADM phase has a specific purpose and associated objectives. Objective 1 refers to development of the Target Data Architecture, which belongs to Phase C: Information Systems Architectures. Therefore, 1 matches C. Objective 2 refers to development of the Target Business Architecture, which is the purpose of Phase B: Business Architecture. Therefore, 2 matches B.

Objective 3 describes creation of a high-level aspirational vision of capabilities and business value. That is the defining purpose of Phase A: Architecture Vision. Therefore, 3 matches A. Objective 4 refers to identifying candidate Architecture Roadmap components based on the gaps between Baseline and Target Technology Architectures. This is associated with Phase D: Technology Architecture, where the target technology state is defined and gaps are used to identify roadmap components. Therefore, 4 matches D.

Putting these together gives the sequence 1C-2B-3A-4D, which corresponds to Option A. This mapping reflects the standard TOGAF ADM flow from vision, to business, to information systems, and then to technology architecture development.
