To answer this question, you need to understand the concept of "dynamic file include" mechanisms in web applications and the attack techniques used to exploit them.
Option A) Dynamic File Attack - This option is incorrect because "dynamic file attack" is not a recognized attack technique used to exploit "dynamic file include" mechanisms in web applications.
Option B) Remote File Inclusion - This option is correct because "remote file inclusion" is a common attack technique used to exploit "dynamic file include" mechanisms in web applications. It involves an attacker including a remote file into a web application, which can allow them to execute malicious code or gain unauthorized access.
Option C) Dynamic Data Attack - This option is incorrect because "dynamic data attack" is not a recognized attack technique used to exploit "dynamic file include" mechanisms in web applications.
Option D) Data Dynamics - This option is incorrect because "data dynamics" is not a recognized attack technique used to exploit "dynamic file include" mechanisms in web applications.
The correct answer is B) Remote File Inclusion. This option is correct because "remote file inclusion" is a well-known attack technique used to exploit "dynamic file include" mechanisms in web applications.
