<image>The Lewis structure for the molecule CO is shown below. What is one of the limitations of using this Lewis structure to represent the molecule? <image 1> 
A. The Lewis structure shows ten valence electrons which is not the correct number.
B. The Lewis structure shows the electrons as distributed evenly between the carbon and oxygen but they are not.
C. The Lewis structure should show the intermolecular forces present, but it does not.
D. The Lewis structure shows the bond between carbon and oxygen as a triple bond but the real bond is actually a double bond.
E. The Lewis structure shows that the molecule has a linear shape but it is actually a bent/v-shape substance.

Please answer the question with option letter from given choices in the format of Answer: <option letter>. You FIRST think about the reasoning process as an internal monologue and then provide the final answer. The reasoning process MUST BE enclosed within <think> </think> tags.
