In a way A is also correct, because for water to freeze there has to be a "starting point", which is usually an irregularity of the surrounding. So liquid water can get below 0 degrees celsius. As a science teacher he knows that, but he also knows questions on this show won't go this deep.
one of the most amazing CoB songs I know. The whole album is pure art, but this song (together with Silent Night, Bodom Night) makes my heart beat at 240 beats per minute :P
Pity their newer songs are more and more aimed on what people want them to make, instead of what they like themself.
