From the following date , mark the opation(s) where `Delta H` is correctly written for the given reaction .
Given: `H+(aq) +OH-(aq) to H_(2)O(l),`
`DeltaH=-57.3 kJ`
`DeltaH_(solution) HA(g)=-70.7 kJ"mole"`
`DeltaH_(solution) BOH(g)=- 20 kJ"mole"`
`DeltaH_("ionzatoin") ` of `HA=15 kJ//"mole"` and BOH is a strong base.

A

`{:("Reaction",DeltaH_r(kJ//"mol")),((A)HA(aq)+BOH(aq)toBA(aq)+H_2O,-42.3):}`

B

`{:("Reaction",DeltaH_r(kJ//"mol")),((B)HA(g)+BOH(g)toBA(aq)+H_2O,-93):}`

C

`{:("Reaction",DeltaH_r(kJ//"mol")),((C )HA(g)toH^+(aq)+A^(-)(aq),-55.7):}`
