A)                 \[\Delta {{H}_{\text{soln}}}=\Delta {{H}_{3}}-\Delta {{H}_{1}}-\Delta {{H}_{2}}\]

B)                 \[\Delta {{H}_{\text{soln}}}=\Delta {{H}_{1}}+\Delta {{H}_{2}}+\Delta {{H}_{3}}\]

C)                 \[\Delta {{H}_{\text{soln}}}=\Delta {{H}_{1}}+\Delta {{H}_{2}}-\Delta {{H}_{3}}\]

D)                 \[\Delta {{H}_{\text{soln}}}=\Delta {{H}_{1}}-\Delta {{H}_{2}}-\Delta {{H}_{3}}\]
