Show answer and explanation

Answer: B. Percent-Encoding (URL Encoding)

• Answer: B
• Explanation: Percent-encoding (URL encoding) converts unsafe or reserved characters into a % followed by a two-digit hexadecimal representation (e.g., a space becomes %20). Cyberattackers sometimes use double URL encoding or uncommon percent encodings to trick poorly configured firewalls into letting malicious inputs pass through.
