Sort this list of historical modems from lowest to highest bandwidth, with the lowest on the top and the highest on the bottom.

• A. Bell 101 @ 110 bits/s, Bell 103 @ 300 bits/s, Modem 1200 @ 1.2 kbit/s, Modem 2400 @ 2.4 kbit/s, VDSL @ 52 Mbit/s, MDSL @ 2.32 Gbit/s
• B. Bell 101 @ 110 bits/s, Modem 1200 @ 1.2 kbit/s, Bell 103 @ 300 bits/s, Modem 2400 @ 2.4 kbit/s, VDSL @ 52 Mbit/s, MDSL @ 2.32 Gbit/s
• C. Bell 103 @ 300 bits/s, Bell 101 @ 110 bits/s, Modem 2400 @ 2.4 kbit/s, Modem 1200 @ 1.2 kbit/s, VDSL @ 52 Mbit/s, MDSL @ 2.32 Gbit/s
• D. Bell 101 @ 110 bits/s, Bell 103 @ 300 bits/s, Modem 2400 @ 2.4 kbit/s, Modem 1200 @ 1.2 kbit/s, VDSL @ 52 Mbit/s, MDSL @ 2.32 Gbit/s

Answer: (A)

Sorting by bandwidth means lining up data rates from the smallest to the largest, remembering the unit scale: bits per second, kilobits per second, megabits per second, and gigabits per second. The speeds given go 110 bps, 300 bps, 1.2 kbps, 2.4 kbps, 52 Mbps, and 2.32 Gbps. When you place them from smallest to largest, you get: Bell 101 at 110 bits/s, Bell 103 at 300 bits/s, Modem 1200 at 1.2 kbit/s, Modem 2400 at 2.4 kbit/s, VDSL at 52 Mbit/s, and MDSL at 2.32 Gbit/s. This sequence puts the lowest speeds at the top and the highest at the bottom, which matches the correct order.
