A Correct answer
Explanation

VSB (Vestigial Sideband) modulation is used for video transmission in TV broadcasting because it conserves bandwidth while maintaining picture quality. VSB removes one sideband almost completely and leaves a vestige (trace) of the other, making it more bandwidth-efficient than DSB or SSB for video signals.
