WhyLower sideband is the amateur convention for voice communications on the 160, 75, and 40 meter bands. 160, 75, and 40 meters sit below the 14 MHz convention line, where amateur practice uses lower sideband for voice, answer B. Upper sideband is used above that line instead, and neither of B's alternatives (suppressed or double sideband) name what's actually in common use on these three bands.
