Comprehensive and Detailed Explanation From Exact Extract:
The CPRE handbook explains that Requirements Engineering demands effort early in the life cycle:
stakeholder analysis, elicitation workshops, modeling, documentation and validation all consume time and resources. These costs are immediate and visible. However, the benefits-reduced rework, fewer defects, better alignment with needs and lower project risk-mainly materialize later during development, operation and maintenance. Thus, RE is an investment with delayed payoff. Option A is wrong because benefits are long-term. Option C is inverted: the more risk an organization is willing to accept, the less RE it may perform.
Therefore statement B is correct.

Comprehensive and Detailed Explanation From Exact Extract:
The syllabus distinguishes categories of RE tools: office tools (general purpose), documentation of knowledge about requirements (e.g., wikis, requirements repositories), management of requirements (for traceability, attributes, baselines), management of RE process (workflow and task support) and others. Office tools can be used but have significant limitations-especially for traceability-so A is overstated. Requirements- management tools deal with requirements objects and links, not workflow (C). Process-management tools handle workflow (B). Documentation tools, such as wikis or collaborative repositories, support sharing and collaboratively editing requirements knowledge, which makes D correct.

Comprehensive and Detailed Explanation From Exact Extract:
The phrase template specifies that an optional condition comes first, then subject, action, objects and finally an optional restriction. Options A-C respect this order and provide all elements: condition ("If/When ..."), subject ("system", "control unit", "printer"), action, object and a final restriction. In D the time restriction is placed at the beginning and the condition ("upon receiving a critical alert") is embedded incorrectly, violating the template's structure. In E, the object of the action ("what" the system shall display) is missing, so the sentence is incomplete. Thus, D and E do not comply.
