B) is the best description.
The water molecule is indeed polar covalent. The bonds between each hydrogen and the oxygen are mostly sharing both electrons. The difference between the electronegativity of the hydrogens and the oxygen atom gives the molecule a dipole moment (making it polar).
Although water can dissociate into H+ and OH- the percentage of molecules that do this is very small.

B! Its 3 atoms are linked through covalent bonds (2), so it is a molecule. It is polar: it has a high dipole moment due to: the difference of electronegativity between the oxygen atom and the hydrogen atoms, the bond angle and the two lone electron pairs of the oxygen atom! The residual charges in the dipole are less than unity (taking one electron as unity of negative charge) and their sum is zero, so it is not ionic.

B - H20 is a polar molecule and the dipole moments are strong enough to create surface tension in and put ions into solution. It isn't ionic - ionic means with charged ions (not partial charged dipole) example is Na+ Cl - (notice the +, - charges when written there are NO COV. BONDS there are IONIC BONDS) . Learn your basic chemistry well - it makes good doctors! :)

b. h2o is a polar covalent molecule
it can't be an ionic compound because there is no overall charge on the molecule

Its definitely not A. Its a covalent compound,not sure if its B or C,but im gonna go with the guys above me.
It cannot be an ionic compound. Ionic compounds are compounds comprising of a metal and a non-metal. H20 does not have any metals.

a) ionic compound. Hydrogen and Oxygen share a covalent bond that results in an ionic charge

B.
coz H2O is not an ionic compuond!
coz H2O is polar!
coz H2O has high dipole moment!

B definitely. There is a tiny bit of ionisation (hence pH) but the vast majority is polar covalent (that is why it is such a good solvent!)

B.. the oxygen pulls the electron from the hydrogen toward itself but does not totally dissociate it.
