Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The upload is denied because the Deny statement applies to all uploads.
The explicit Deny statement without any condition applies to all uploads, overriding any Allow statements. Option A is incorrect because the Deny statement still applies even without a Principal (since it's attached to the user). Option B is incorrect because there is no size condition; the Deny applies to all uploads regardless of size. Option C is incorrect because the explicit Deny overrides the Allow for s3:PutObject.
