Why are algorithms like Bcrypt and Argon2 heavily favored over fast algorithms like MD5 or SHA-256 for storing user passwords?

A. They compress the password string to save database space
B. They can be easily reversed if the user forgets their password
C. They are exclusively used by government agencies
D. They intentionally utilize 'key stretching' to make computations slow and resource-intensive, crippling brute-force hardware attacks
