From the following data, mark the option(s) where `DeltaH` is correctly written for the given reaction.
Given : `H^(+)(aq)+OH^(-)(aq)rarrH_(2)O(l),DeltaH=-57.3 " kJ"`
`" "DeltaH_("solution")" of "HA(g)=-70.7 " kJ"//"mol"`
`" "DeltaH_("solution")" of "BOH(g)=20 " kJ"//"mol"`
`DeltaH_("ionization")` of HA = 15 kJ/mol and BOH is a strong base.

A

`{:("Reaction",DeltaH_(r)(KJ//"mol")),(HA(aq) + BOH(aq) rarr BA(aq) + H_(2)O,-42.3):}`

B

`{:("Reaction",DeltaH_(r)(KJ//"mol")),(HA(q) + BOH(q) rarr BA(aq) + H_(2)O,-93):}`

C

`{:("Reaction",DeltaH_(r)(KJ//"mol")),(HA(q) rarr H^(+)(aq)=A^(-)(aq),-55.7):}`

D

`{:("Reaction",DeltaH_(r)(KJ//"mol")),(B^(+)(aq)+OH^(-)(aq) rarr BOH(aq),-20):}`
