The correct answer is (a) suppressed-carrier

To explain: DSB-SC stands for Double Side Band- Suppressed Carrier. In SBSC, the carrier is suppressed and only the two sidebands are transmitted. In DSB-SC all the frequencies produced by amplitude modulation are symmetrically arranged above and below the carrier frequency.
