According to the BABOK Guide, the task of prioritizing requirements assesses the value, urgency, dependencies, and risks associated with requirements and designs to ensure that analysis and delivery work is done on the most important ones at any given time1. Prioritization is an ongoing process, with priorities changing as the context changes. The task of prioritizing requirements creates just one output, which is requirements (prioritized). This output is a list or a model of requirements and designs that have been assigned a level of importance or urgency relative to other requirements and designs2. The output of requirements (prioritized) is used as an input for other tasks, such as managing solution scope and requirements, assessing proposed solutions, allocating requirements, and validating requirements3.

The other options are not correct outputs of the task of prioritizing requirements:

Validated requirements are an output of the task of validating requirements, which ensures that the requirements and designs support the delivery of value, fulfill the stakeholder needs, and meet the quality standards3.

Requirements rankings are not a formal output of the task of prioritizing requirements, but rather a possible technique to assign a numerical value to each requirement or design based on a set of criteria2.

Requirements assessment is not an output of the task of prioritizing requirements, but rather a possible technique to evaluate the impact, feasibility, and value of requirements and designs2. References:
