The local library has several public desktops and is concerned about PCs being opened and components being stolen. Which of the following could prevent this?
The correct answer is D. Use security screws to prevent the case from being opened. The concern is preventing internal components from being physically removed, which requires restricting access to the inside of the case itself. Security screws require a special tool to remove, making it impractical to open the case in a public setting.

Why each option
The concern is preventing internal components from being physically removed, which requires restricting access to the inside of the case itself. Security screws require a special tool to remove, making it impractical to open the case in a public setting.
Cable locks secure the entire chassis to the desk, preventing theft of the whole PC but not stopping someone from opening the case while it remains tethered.
Biometrics identify and log users but provide no physical barrier against someone opening a PC case.
Resource monitoring software tracks CPU, memory, and disk usage and has no capability to prevent physical hardware access.
Security screws (also called tamper-resistant or Torx-style security screws) replace standard Phillips or flat-head screws on the PC case, requiring a special bit that most opportunistic thieves will not have on hand. This directly addresses the threat of someone opening the case and removing RAM, GPUs, or other valuable components. It is a passive, always-on physical control with no software or network dependency.
