When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule?

Here is the full question with choices: When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule, .?

A. the hydrogen atom becomes partially positive

B. the electronegative atom becomes strongly positive

C. the hydrogen atom becomes partially negative

D. the oxygen atom becomes partially negative

The answers are A and D. The oxygen holds onto the electrons more of the time so is slightly negative, making H slightly positive and thus making a polar covalent bond.
