The correct answer is B.

OBJ-1.7: SQL injection is a code injection technique that is used to attack data-driven applications. SQL injections are conducted by inserting malicious SQL statements into an entry field for execution. For example, an attacker may try to dump the contents of the database by using this technique. A common SQL injection technique is to insert an always true statement, such as 1 == 1, or in this example, 7 == 7. In this case, the SQL injection is evidenced by the SQL statements being sent to the web application hosted by WordPress. XML Injection is an attack technique used to manipulate or compromise an XML application or service’s logic. The injection of unintended XML content and/or structures into an XML message can alter the application’s intended logic. Cross-Site Scripting (XSS) attacks are a type of injection in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in a browser side script, to a different end-user. A directory traversal attack aims to access files and directories that are stored outside the webroot folder. By manipulating variables or URLs that reference files with “dot-dot-slash (../)” sequences and its variations or using absolute file paths, it may be possible to access arbitrary files and directories stored on the file system, including application source code or configuration and critical system files.
