Explanation

Encryption protects data at rest, in transit, and (with modern techniques) in use - covering all layers of the technology stack. It is the only method that renders data unintelligible to unauthorized parties at every layer. Hashing (A) is a one-way transformation suitable for integrity checks, not confidentiality. Obfuscation (B) provides weak, easily reversible protection. Tokenization (D) replaces sensitive values with tokens and works well for specific use cases (e.g., payment data) but is not a general-purpose stack-wide data protection method.
