c. SO2. S shares 8 electrons total with the two O\'s. S contributes 4 electrons total to the sharing; 2 to each of the two O\'s. So S has one lone pair of electrons left ( remember S is in group VI i.e. should have 6 electrons in its outermost shell). This lone pair of electron makes the molecule to be bent. Solution c. SO2.
