8) a -- Single Sideband-Suppressed Carrier is the name of the primary analog HF voice mode.
9) c -- This organization supports a worldwide beacon network on 20 through 10 meters - very handy! See their Web site for details and schedules.
10) a -- 30 meters is a refuge for the CW and digital operator, although still a secondary allocation to amateurs.
11) a -- 60 meters consists of five fixed-frequency channels where only USB voice is permitted.
12) d -- The lower the band, the lower maximum data rate becomes, down to 1200 bps in the HF bands.
