Complete this sentence in regard to the level of abstraction.

According to the BABOK® Guide, the level of abstraction is the degree to which a requirement or design statement is general or specific. Requirements need to say what needs to be done, not how to do it. This means that requirements should focus on the desired outcome or value, not the implementation details or solution design. How to do it is the responsibility of the solution provider, not the business analyst. Therefore, option C completes the sentence correctly. References: BABOK® Guide, page 11; Business Analysis Expert Certification, CCBA® | IIBA®, section “What Should I know to be CCBA Certified?”
