Explanation:
From strongest to weakest, the intermolecular forces rank in the following way:
Strongest: Hydrogen bonding. This occurs when compounds contain #"O"-"H"# , #"N"-"H"# , or #"F"-"H"# bonds. ...
Less strong: Dipole-dipole forces. ...
Weakest: London Dispersion Forces.
Do not ionize in solutions
Poor conductors of electricity/heat

I would say C is the most correct.
In D it depends on what water source you're using. Let's say it is a waterfall, then the source of the water (melting ice or a lake) may disappear in the future.
If you're using underwater "windmills" placed in the ocean, then you would expect it to last a while as the ocean will not disappear in the near future.
