Explanation

Encryption protects data confidentiality by converting plaintext into ciphertext that only an authorized recipient with the correct key can read. For emailing PII securely, encrypting the email or attachment ensures only the intended HR recipient can access the content. Digital signatures (A) provide authentication and non-repudiation, not confidentiality. Hashing (B) is a one-way function used for integrity verification, not confidentiality. A secret key alone (C) is a component of encryption, not a complete solution on its own.
