A) Carbon dioxide
B) Silicon dioxide
C) Nitrogen dioxide

Hi, this is how I would approach this question. For this example it is enough to know how to draw the molecules to solve it, and we find that the answer is A. If you’re not familiar with this I recommend learning the following 2 topics: 1. How to draw lewis dot structures and 2. VSEPR theory.
I really appreciate your help. Thank you
