formation means it's an exothermic reaction, hence it's a negative value (favorable reaction). A positive enthalpy is an endothermic reaction (non favorable reaction) . Or the answer D

B.) because of the law of conservation of energy There is not " law of conservation of enthalpy" , it is Hess's Law or law of conservation of energy or First law of thermodynamics. https://en.wikipedia.org/wiki/Hess's_law
