Answer and explanation

Correct answer

D. To increase the time required for brute-force attacks.

Why

Increasing the work factor of BCrypt over time makes password hashes more resistant to brute-force attacks as computational power increases. It increases the time required to compute each hash, making it harder for attackers to guess passwords.
