In TOGAF, deliverable 2 is correctly identified as Architecture Contracts. These are the formal joint agreements between development partners, sponsors, and in some cases implementation organizations, covering the expected deliverables, quality measures, and fitness-for-purpose of the architecture. Their role is to ensure that architecture intent is translated into governed and measurable commitments. Architecture Contracts are especially important in implementation governance because they define expectations, conformance requirements, and accountability between parties involved in the architecture and delivery process.

Deliverable 3 is the Request for Architecture Work. This is the formal initiating document sent from the sponsoring organization to the architecture function to trigger the start of a new architecture development cycle. It provides the initial authorization to begin the architecture effort and acts as a formal signal that architecture work is needed. It is one of the recognized inputs used to begin structured ADM activity.

The other options do not match the definitions given. The Architecture Definition Document describes the architecture itself, not joint agreements. A Change Request is used later to propose modifications. Architecture Vision and Architecture Requirements Specification are different ADM outputs with different purposes.

Therefore, the correct mapping for labels 2 and 3 is Architecture Contracts and Request for Architecture Work, which is Option B.
