Best answer
Correct choice is (c) VSB

Easiest explanation: Vestigial Sideband Modulation (VSB) is a type of amplitude modulation in which the carrier and only one sideband is completely transmitted and the other sideband is partly transmitted. Thus, video signals are transmitted using VSB modulation.
