Which compound have electrovalent, covalent, coordinate as well as hydrogen bond ?

A) $\ce{[Cu(H2O)4]SO4.H2O}$
B) $\ce{[Zn(H2O)6]SO4.H2O}$
C) $\ce{[Fe(H2O)6]SO4.H2O}$
D) $\ce{[Fe(H2O)6]Cl3}$

Answer given:

Option (A)

My approach and doubt:

All the compounds contain electrovalent, covalent as well as coordinate bonds hence the deciding factor is hydrogen bonding. (D) clearly would not have hydrogen bonding. Now my doubt is in comparison of (a),(b),(c). I know that in structure (A) inwhich is $\ce{CuSO4.5H2O}$$\ce{CuSO_4.5H_2O}$ the fifth water of crystallisation$\ce{H_2O}$ which is hydrogen bondedsomething that was taught to me earlier.

But what aboutMy Doubt:
Yes I get the answer to the given mcq problem above but I was not able to understand the case of (B) and (C). I think that the ? If$\ce{H_2O}$ inside the water moleculecoordination sphere are bonded through dative bond and the $\ce{SO_4}$ outside by ionic bonds but I am not able to understand the coordinate sphere denotednature of bond formed by "$\ce{.H2O}$ " is$\ce{.H_2O}$" present outside the main coordination sphere given in the complexes above. Would they not form hydrogen bonded thenbond? The answer scheme doesn't think so. So if they don't what typeis the nature of bond does it formformed by these "$\ce{.H_2O"}$ !?
