If you install a single pole breaker you will only be able to supply 120 volt loads from the panel. A double pole breaker will allow you to run either 120 or 240 volt loads from the panel.

If you installed a single pole breaker only every other buss finger would be hot in your panel.

Double pole, because that supplies 240V. Also because no one manufactures a single pole 100A breaker.
