Correct answer & explanation
✓
IAM policy with a condition for aws:MultiFactorAuthPresent
An IAM policy with a condition that checks aws:MultiFactorAuthPresent can require MFA for API calls, enforcing MFA usage. Option A is wrong because AWS Organizations SCPs can enforce policies at the account level but cannot require MFA for individual IAM users without an accompanying IAM policy. Option B is wrong because AWS Config can detect non-compliance with MFA rules but cannot enforce the policy itself. Option D is wrong because AWS CloudTrail is used for logging API activity, not for enforcement.
