Why each option

USB technology allows for hot plugging of devices, meaning they can be connected or disconnected while the computer is running, and can support up to 127 peripheral devices through the use of hubs.

AUSB supports hot plugging.Correct

USB supports hot plugging, enabling users to connect and disconnect devices without needing to power down or restart the computer, enhancing user convenience.

BYou can connect up to 127 peripheral devices to a single USB port.Correct

Through the use of USB hubs, a single USB host controller can manage a tiered star topology that theoretically supports up to 127 peripheral devices.

CYou can connect up to 16 peripheral devices to a single USB port.

The limit of 16 peripheral devices is incorrect; USB's architecture with hubs allows for significantly more, up to 127.

DUSB does not support Plug n Play installation.

USB is designed for and fully supports Plug and Play (PnP) installation, which automatically configures and installs drivers for connected devices.
