Selected Answer: D
D. N and 2.4GHz Here’s why: 802.11n (Wi-Fi 4): This standard supports both 2.4GHz and 5GHz frequencies, but using 2.4GHz provides better range and compatibility with a wide variety of IoT devices1. It offers speeds up to 600 Mbps, which is sufficient for most IoT applications. 2.4GHz Frequency: This frequency band has better penetration through walls and obstacles, making it more reliable for IoT devices that might be spread throughout a home or office
