Explanation

Using a list of common passwords to systematically attempt logins against a remote system is a brute-force attack (B) - specifically a dictionary variant - because the attacker is cycling through candidate credentials until one succeeds. DoS (A) is wrong because that attack floods a system to make it unavailable, not to gain access. SQL injection (C) exploits database query vulnerabilities in web inputs, not login credential guessing. Phishing (D) tricks users into voluntarily revealing credentials through deception, requiring human interaction.

Memory tip: Think "brute force = try until you break in" - it's the digital equivalent of trying every key on a keyring. If the attack automates guessing, it's brute-force.
