Explanation

This question tests knowledge of wireless technology standards and their throughput capabilities relative to each other for a home networking use case.

Common mistakes.

B. Satellite internet provides wide geographic coverage but has high latency and throughput well below modern 802.11 Wi-Fi, making it unsuitable as the fastest home wireless option.
C. Bluetooth is a short-range personal area network (PAN) technology designed for low-power device pairing with a maximum throughput far below Wi-Fi, and is not a home internet connectivity standard.
D. 3G cellular provides mobile broadband with maximum theoretical speeds of around 21 Mbps (HSPA+), which is significantly lower than modern 802.11 Wi-Fi standards used in home networks.

Concept tested. IEEE 802.11 Wi-Fi performance for home wireless networking
