In which of the following reactions is ΔE closest in value to ΔH?

a) HNO3(aq) + Na2(CO3)(aq) = NaNO3(aq) + H2O(l) + CO2(g)
b) HCl(aq) + NaOH(aq) = H2O(l) + NaCl(aq)
c) KClO3(s) = KCl(s) + (3/2)O2(g)
d) Na(s) + H2O(l) = NaOH(aq) + (1/2)H2(g)

I'm thinking it's C but I'm not sure, thanks!

b) HCl(aq) + NaOH(aq) = H2O(l) + NaCl(aq)
As ΔH = ΔE + PΔV
In this reaction apparently no change in Volume.
