Sandboxing is a security mechanism used to create a controlled environment in which applications can run. This isolation helps to prevent various types of exploits from affecting the entire system or network. In the context of this question, proper sandboxing plays a crucial role in preventing container breakout scenarios.

Container breakout occurs when an application running in a container gains unauthorized access to the host system or other containers. By isolating applications within sandboxes, each container operates independently, limiting its ability to interact with the underlying host system or other containers. This makes it significantly harder for the application to execute malicious actions that could compromise the host.

The other listed exploits do not directly relate to the function of sandboxing. Cross-site scripting is primarily a web security vulnerability affecting web applications, while SQL injection targets databases through improperly sanitized inputs. Denial of service attacks focus on overwhelming a system's resources, which are typically mitigated through other security measures rather than sandboxing. Thus, the correct answer highlights how sandboxing specifically prevents container breakout, enhancing overall system security.
