Acknowledgement and attestationinvolveformal confirmationthat an application is no longer in scope for compliance, auditing, or reporting requirements. This typically includes documentation signed by relevant stakeholders confirming that the software no longer processes, stores, or transmits relevant data.
Data inventory and retention (A)is related to managing data assets, not software scope confirmation.
Right to be forgotten (B)pertains toprivacy laws (e.g., GDPR), allowing individuals to request data deletion.
Due care and due diligence (C)focus on security best practices rather than software applicability.

The SMS OTP (One-Time Password) method is more vulnerable to interception compared to TOTP (Time- based One-Time Password) because SMS messages can be intercepted through various attack vectors like SIM swapping or SMS phishing. TOTP, on the other hand, generates codes directly on the device and does not rely on a communication channel like SMS, making it less susceptible to interception.
