The correct answer is:

(c) calcium or magnesium chloride

Anti-freeze materials commonly use chemicals like ethylene glycol or propylene glycol mixed with water. While calcium and magnesium chloride are sometimes used in de-icing applications, they are not typically part of the anti-freeze mixtures used in engines. Kerosene and sugar solutions are not used in anti-freeze mixtures either.
