Explanation
According to the TOGAF template for Architecture Principles, the Rationale section should describe the relationship to other principles, as well as the business benefits and the intentions of adhering to the principle.
The Rationale section should use business terminology and point to the similarity of information and technology principles to the principles governing business operations. The Rationale section should also explain how the principle supports the achievement of the business objectives and key architecture drivers. References:

The implications section of the TOGAF template for Architecture Principles should describe the relationship to other principles. Implications are statements that describe how a principle will impact other principles, as well as other aspects of the enterprise such as business processes, organizational structures, roles and responsibilities, standards, etc. Implications help to identify potential conflicts or synergies among principles and to assess their feasibility and applicability.

Explanation
Strategy Portfolio Project Solution Delivery are the four purposes that typically frame the planning horizon, depth and breadth of an Architecture Project, and the contents of the EA Repository. They correspond to different levels of abstraction and granularity in the architecture development process. Reference: The TOGAF Standard, Version 9.2 - The Open Group, Section 2.4 Architecture Repository.

An EA Capability is the ability of an organization to perform enterprise architecture effectively and efficiently. It involves establishing and maintaining the appropriate organization structures, roles, responsibilities, skills, processes, tools, and governance mechanisms to support the development and use of enterprise architecture. An EA Capability enables the organization to align its business and IT strategies, deliver value from its investments, manage change and complexity, and improve its performance and agility12 Reference: 1: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 44: Introduction 2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 45: Establishing and Maintaining an Enterprise Architecture Capability

According to the TOGAF standard, the deliverables that match the descriptions are as follows:
1 Architecture Principles: These are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in which an organization sets about fulfilling its mission1. They reflect a level of consensus among the various elements of the enterprise, and form the basis for making future IT decisions1.
2 Architecture Contracts: These are the joint agreements between development partners and sponsors on the deliverables, quality, and fitness-for-purpose of an architecture2. They are used to ensure that the architecture is implemented and governed according to the agreed-upon specifications and standards2.
3 Request for Architecture Work: This is a document that is sent from the sponsoring organization to the architecture organization to trigger the start of an architecture development cycle3. It defines the scope, schedule, budget, deliverables, and stakeholders of the architecture project3.
4 Architecture Requirements Specification: This is a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture4. It defines the requirements for each architecture domain, as well as the relationships and dependencies among them4.
