Final answer:
A digital video recorder (DVR) being 'hogged' by one member of the family is similar to how oxygen 'hogs' electrons in a water molecule allowing it to form polar covalent bonds with hydrogen.
Step-by-step explanation:
A digital video recorder (DVR) being 'hogged' by one member of the family is similar to how oxygen 'hogs' electrons in a water molecule allowing it to form polar covalent bonds with hydrogen.
Oxygen is more electronegative than hydrogen, so the electrons are drawn towards oxygen, resulting in oxygen acquiring a slight negative charge and hydrogen acquiring a slightly positive charge. This unequal sharing of electrons is what makes the water molecule polar.
Thus, the correct answer is C. polar covalent bonds.
