Keywords: 'To ensure the requirements are delivered according to customer expectations'. I am going with 'Acceptance Criteria'. See pg 217 BABOK v3: Acceptance criteria are used to define the requirements, outcomes, or conditions that must be met in order for a solution to be considered acceptable to key stakeholders. Evaluation criteria are the measures used to assess a set of requirements in order to choose between multiple solutions.

Requirements Attribute, BABOK V3 page 45 • Priority: indicates relative importance of requirements. Priority can refer to the relative value of a requirement or to the sequence in which it will be implemented.

A- Prioritization is the act of ranking requirements to determine their relative importance to stakeholders. When a requirement is prioritized, it is given greater or lesser priority. Priority can refer to the relative value of a requirement, or to the sequence in which it will be implemented. Prioritization is an ongoing process, with priorities changing as the context changes. Inter-dependencies between requirements are identified and may be used as the basis for prioritization. Prioritization is a critical exercise that seeks to ensure the maximum value is achieved.

acceptance criteria: Criteria associated with requirements, products, or the delivery cycle that must be met in order to achieve stakeholder acceptance. I will go with D.

I'm thinking it's A because Constraint isn't even a requirements attribute and Acceptance Criteria is only considered a Requirements Attribute from v2. Priority is the only one that relates to order of importance of completion. Frankly, I'm not getting caught up in a v2 question.

I think you're all wrong, question clearly states: inter-dependencies with other requirements =constraints, = BA should consider constrants. given answer is correct

I think it's A 3.4.4.6 • Priority: indicates relative importance of requirements. Priority can refer to the relative value of a requirement or to the sequence in which it will be implemented.

I will take D. Reason being that the question asked "To ensure the requirements are delivered according to customer expectations" so Acceptance Criteria should be included in the Document

Inter-dependencies between requirements are identified and may be used as the basis for prioritization. Prioritization is a critical exercise that seeks to ensure the maximum value is achieved.Page-87

Priority: indicates relative importance of requirements. Priority can refer to the relative value of a requirement or to the sequence in which it will be implemented.Page-45

Question says inter-dependant, hence its Priority

I think Priority is the answer. Only Priority and Unique Identifier (absolute reference) are the two attributes listed as options, mentioned in the BAPM - Info Mgmt KA
