Answer:
B. Bluetooth technology.
Explanation:
A hardware platform can be defined as a collection of hardware such as an input hardware and output hardware device that are compatible with each other and the software application or program to be executed. All hardware platforms have their respective low level or high level machine language that are compatible with the software application. Some examples of a hardware devices are speakers, monitor, x86, i860, keyboard, MIPS, scanner, central processing unit (CPU) video game consoles (joysticks), IBM Z, ARM, unisys, powerpc, SPARC etc.
Generally, all hardware devices are connected with one another through the use of a wire such as cables or wirelessly such as Bluetooth, infrared etc.
Hence, not all hardware is connected with wires, some hardware might be connected wirelessly with Bluetooth technology.
A Bluetooth technology can be defined as a wireless standard used for transmitting and receiving data over a short-range of distance. Therefore, the operating radio frequency of a Bluetooth technology is 2.45 Gigahertz and for a distance of about 10 meters (30 feet).

The X's have been correctly placed in the chart
A surge suppressor, which is also commonly known as a surge protector, is an important equipment that helps prevent damage to electric components from an unexpected increase of voltage. Let’s assume that you are living in a county where the effective utility voltage is between 110 to 120 volts. Assume that the accepted peak voltage should not be anything higher than 170 volts. If there is a surge and this surge reaches peak levels of 170 volts and higher, surge suppressors should jump in and prevent the peak AC voltage from going above the threshold.
People tend to confuse line conditioners and surge suppressors. While surge suppressors protect components from surges, line conditioners are built to make up for the loss of voltage from the lines. It does so by storing some power energy. This stored energy can later be modified and used when the volts drops to the desired 110 volts.
A UPS has DC battery power that provides battery backup power when the electricity goes off or when the levels of voltage drop significantly. When the electricity goes off means that the voltage is at 0 volts and it is the work of the UPS to kick its backup power in.
A negative externality is when a good costs much greater than what the consumer pays for it. Since you did not provide the possible answers, use this explanation to find the correct answer among the ones you might have.
