Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Requirement for 100% code coverage in unit tests.
Why it's wrong here
Code coverage is a quality metric, not a supply chain security control.

Requirement to use proprietary code only.
Why it's wrong here
Open-source is ubiquitous; banning it is impractical.
- ✓
Requirement for an SBOM for all delivered software.
Why this is correct

Requirement for the supplier to perform a full system wipe.
Why it's wrong here
