Which undergraduate course would be the best choice?

I am looking into becoming a veterinarian. When I did my research it said that I had to take a undergraduate course. It gave me six choices: animal biology, organic and inorganic chemistry, physics, genetics, zoology, and cellular biology. They said I had to be in a 4years college and 4 years of veterinary medicine. I just want to know which choice of a 4 year college I should choose. Zoology and animal biology seems interesting to me.
