Answer options

• A. Ransomware
• B. Phishing
• C. DDoS
• D. Social engineering
• E. Spoofing

Correct answer: A

Explanation

The correct answer is Ransomware, as it specifically encrypts data and restricts access until a ransom is paid. Phishing aims to deceive users into revealing personal information, DDoS overloads services to disrupt access, Social engineering manipulates individuals into divulging confidential information, and Spoofing involves disguising a communication from an unknown source as being from a known, trusted source.
