Answer to Question 1

(This question could also be asked about CF4 or CO2.)
The bonds in this compound are polar due to the difference in their electronegativity values. However, the molecule is not polar because the molecule is symmetrical, which means that the polar forces in different directions balance each other out. In this case, the overall distribution of electrons in the molecule is even.

Answer to Question 2

B
