Why is B incorrect?

Is it because of the “most but not all” clause?

Hello @dannyod,

In short, you are exactly right. Line 16 tells us that the grains of magnetite in magma align themselves with the earth's magnetic field. This is presented as something that generally happens, without explicitly saying how often. "Most but not all" is quite specific, and there is nothing to support that here. It is possible that every single grain of magnetite does this.
