The table name is DeviceInfo, but in Microsoft Defender for Endpoint the correct table is DeviceInfo (it exists). However, the query may fail if the device is not onboarded. Option C is correct. Option A (risk score) would still show if device exists. Option B (OS) is not a filter. Option D (permissions) would cause an error, not empty results.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
