Consider the following halogen containing compounds

I. \[CHC{{l}_{3}}\]

II. \[CC{{l}_{4}}\]

III. \[C{{H}_{2}}C{{l}_{2}}\]

IV. \[C{{H}_{3}}Cl\]

V.

The compounds with a net zero dipole moment are

A)  II and V only    

B)  III only

C)  III and IV only                  

D)  I and IV only

E)  II only

Correct Answer: A
