What is a patch?

• A. Hotfix
• B. Machine.config
• C. Syhunt Hybrid
• D. Patch

Answer: (D)

A patch is a software update that fixes problems in a program, such as bugs or security vulnerabilities, by applying changes to the code or data. It’s the general term for an update you install to make the software safer or more reliable, often delivered as a patch file or through an updater.

In this context, the best match is the word that denotes the general update itself. The other options point to unrelated things: a hotfix is a rapid, targeted patch for a critical issue (still a patch, but not the broad concept being asked), a configuration file path (machine.config), and a vulnerability scanner tool (Syhunt Hybrid).
