C Correct answer
Explanation

This is Directory Traversal (aka Path Traversal). The URL contains encoded sequences (like %2e for '.' and %2f for '/') that attempt to navigate up the directory tree to access /etc/passwd. This attack bypasses web root restrictions by manipulating file paths. Buffer overflow (A) sends excessive data. XSS (B) injects scripts. Obfuscation (D) hides code, not an attack type itself.
