B

Correct Answer

A random value added to a password before hashing to ensure identical passwords produce different hashes and defeat rainbow table attacks

Explanation

Without salt: identical passwords produce identical hashes (rainbow tables work). With salt: each password has a unique random salt prepended, making precomputed attacks infeasible. bcrypt/Argon2 handle salting automatically.
