Final answer:
Bank vaults must have vibration sensors on their walls to detect boundary penetration attempts due to the high security needed to protect valuable items stored within them. The correct option is A) Bank vaults
Step-by-step explanation:
Among the options provided, bank vaults are most likely to require vibration sensors on their walls to detect attempts at boundary penetration attempts due to the high security needed to protect valuable items stored within them. Such advanced security measures are essential in high-security areas where valuable items are stored. Vibration sensors are part of a sophisticated security system that can detect any attempt to drill, cut, or break through a wall, and they are commonly used in banks, museums, and other high-value storage facilities. Libraries, schools, and restaurants typically do not require such high levels of security, and while some might implement various security measures, they are generally less critical than those required for a bank vault.
