Gervald Fis correct on all counts.
a) CaCl(aq) is not a product, because it's the wrong formula.
c) The nonionic species is H2O. It is nitpicking to say that H2O is 10^-7 ionized, because that is vanishingly small.
e) Cl- does not appear in the net ionic equation, because the net ionic equation is H+ + OH- ===> H2O

bde are the answers. In this case we cannot have a solid product because the atoms are more stable in the ion form. In case you dry the solution, you will end up with a solid CaCl2.
