Explanation Option D is correct because Platform Shield Encryption allows you to encrypt standard fields and use them in workflow rules. Platform Shield Encryption uses AES 256-bit encryption to protect sensitive data at rest, while preserving platform functionality12 Option A is incorrect because Cryptography Class is a set of Apex methods for creating digests, message authentication codes, signatures, and encryption. It does not provide a way to encrypt standard fields or use them in workflow rules3 Option B is incorrect because Data Masking is a feature that replaces sensitive data in sandboxes with dummy data. It does not encrypt data in production or allow the use of encrypted data in workflow rules45 Option C is incorrect because Classic Encryption is a feature that encrypts custom fields with 128-bit AES encryption. It does not support standard fields or workflow rules67 References: 1: Salesforce Shield - Data Monitoring & End to End Encryption 2: How Shield Platform Encryption Works 3: Crypto Class 4: Data Masking - Anonymize Sensitive Data 5: Secure Your Sandbox Data with Salesforce Data Mask 6: What's the Difference Between Classic Encryption and Shield Platform Encryption? 7: Salesforce Classic vs. Salesforce Shield Platform Encryption: Which One Do You Need?
