Comprehensive and Detailed in Depth Explanation:

The CMMC Assessment Process (CAP) emphasizes that assessor bias, whether stemming from past experiences or other factors, can compromise the objectivity and integrity of an assessment. John’s preconceptions, based on prior encounters, may lead him to misinterpret evidence, either overly critically or leniently, rather than evaluating the OSC’s practices in their current context. This aligns with CAP’s requirement for assessors to remain impartial and focus on objective evidence specific to each assessment.

Option A (no impact) contradicts CAP’s guidance on bias management. Option C (experience ensures unbiased accuracy) overstates experience’s role, ignoring bias risks. Option D (streamlining via preconceptions) misrepresents bias as beneficial, whereas it risks inconsistency. Option B correctly identifies the potential impact on assessment integrity, making it the correct answer.
