The command uses sqlmap, a powerful SQL injection and database penetration testing tool. The flag -u specifies the target URL, and -dbs instructs sqlmap to enumerate the available databases on the DBMS behind that URL.

Command Breakdown:

-u: Target URL with injectable parameters

-dbs: Retrieve and enumerate all available database names

This is a common first step in identifying vulnerable DBMS structures after confirming SQL injection.

Incorrect Options:

A. Backdoor creation is not the default function of sqlmap.

C. Retrieving SQL statements would require additional options like --trace or --sql-query.

D. Option D is not technically accurate—sqlmap is used for injection and enumeration, not searching statements.
