Answer: (B)

Patch management refers specifically to the process of managing updates for software applications to address vulnerabilities. This involves identifying, acquiring, testing, and installing patches or updates provided by software vendors to fix vulnerabilities, bugs, or other issues in the software. Keeping software updated through regular patch management is crucial for maintaining security, as many vulnerabilities can be exploited by attackers if they remain unpatched.

Effective patch management helps organizations mitigate risks and enhances the overall security posture by ensuring that all systems are running the most secure and stable versions of their software. This process often includes maintaining an inventory of software and versions, monitoring for available updates, and applying these updates in a timely manner to protect against newly discovered security threats.
