B, magnesium and dilute sulfuric acid can react to generate hydrogen, which increases the pressure in the bottle, so B is correct;
C, sodium chloride does not react with water, does not dissolve, does not give off heat, and the pressure in the bottle is constant, so C is wrong;
D, quicklime reacts with water to release a lot of heat, which increases the pressure in the bottle, so D is correct.
So choose C.
