Holy crap, none of the above. My answer is LMNOP dissolves in water.

Something can not dissolve in water unless it is polar. Water pulls polar molecules apart, that equals dissolving. So, right away I can say Hg can not because it is an element. All others I would have to check their polarity. Hope this helps you answer your own question!

a) HCl will dissolve in water to form hydrochloric acid.
b) Cu(NO3)2 - yes. Most nitrates are soluble in water.
c) CH3CH2OH - is ethanol. Most definitely soluble in water.
d) Mercury - very soluble in water. (Practically insoluble.)
e) Ethanitrile. I got a bit stuck on this one and had to search (see link). It is miscible with water (i.e. soluble)

The first three, yes; mercury, no; and the last one maybe but I doubt it.
