To solve for DH of the reaction, we need to find the sum of the products' heats of formation and subtract the sum of the reactants' heats of formation.

DH = [6(-394 kJ/mol) + 6(-286 kJ/mol)] - [-1268 kJ/mol + 0 + 0] 
DH = -3372 kJ/mol - (-1268 kJ/mol) 
DH = -2104 kJ/mol

Therefore, the answer is C, -2812 kJ.
