Are the following spectrums correct? The carrier frequencies are given as an example.

The SSB and DSB-SC spectra look correct to me. I wasn't too familiar with VSB, but a quick google led to these lecture notes from Stanford (here). There is an image (shown below) in the notes which supports your understanding of VSB, so I think you are correct.

(I think the DSB may be DSB-SC as I cannot clearly see the carrier peak shown)

Hope that is of some help
