Answer and explanation
Correct answer
B. To securely hash passwords with a slow algorithm resistant to brute-force attacks.
Why
BCrypt is used for securely hashing passwords because it is a slow algorithm designed to be resistant to brute-force attacks. It uses a work factor to adjust the computational complexity, making it harder for attackers to crack passwords.
