Explanation

Roles contribute to system security by defining access levels based on job requirements (D) - a principle known as Role-Based Access Control (RBAC), where users are granted only the permissions needed for their specific function, minimizing exposure to sensitive resources. Option A is wrong because roles do the opposite: they restrict access, not grant it freely. Option B is incorrect since roles complement authentication mechanisms like passwords rather than replace them. Option C is a distractor - roles actually simplify administration by grouping permissions, reducing management complexity rather than increasing login friction.

Memory tip: Think of roles like job badges in a building - a janitor's badge opens storage rooms, a doctor's opens patient wards, but neither opens the server room. Roles = right access for the right job, nothing more.
