Three Non-Equivalent Lewis Structures for Carbonyl Sulfide,SCO,are Given Below $~~~~~~~~$ A $~~~~~~~~$

Three non-equivalent Lewis structures for carbonyl sulfide,SCO,are given below.Use the concepts of formal charge and electronegativity to choose the structure that is the best representation.

$~~~~~~~~$ A $~~~~~~~~$$~~~~~~~~$$~~~~~~~~$$~~~~~~~~$$~~~~~~~~$ B $~~~~~~~~$$~~~~~~~~$$~~~~~~~~$$~~~~~~~~$ C

A) Structure A,because all the formal charges equal 0.
B) Structure B,because all the formal charges equal 0.
C) Structure C,because all the formal charges equal 0.
D) Structure A,because the negative formal charge resides on the most electronegative atom.
E) Structure C,because the negative formal charge resides on the most electronegative atom.
