Final answer:
To use a wireless keyboard and mouse with a laptop, Bluetooth is the recommended method as it is designed for short-range wireless communications between devices like keyboards, mice, and computers.
Step-by-step explanation:
If you want to use a wireless keyboard and mouse with your laptop computer, the best method to choose would be Bluetooth. This is because Bluetooth is a standard for wireless communication that is designed for short-range connections and is commonly used for connecting peripherals like keyboards and mice to computers. It's also integrated into most modern laptops, which makes it particularly convenient.
Other options listed, such as IEEE 1394 and USB, are wired interfaces, and PS/2 is an older standard that is also wired. Option c, 802.11g wireless, is actually a specification for wireless networking, not typically used for connecting keyboards and mice. Hence, Bluetooth is the most appropriate choice out of the ones given.
