Which of the following would you include in a study designed to test your hypothesis?

a. Inoculate the mouths of a group of Western children with S. mutans.

b. Culture S. mutans from African children, sequence its DNA, and compare to Western S. mutans.

c. Switch a group of East African children to a diet that contains sucrose.

d. Check for S. mutansin the mouths of Western children after their cavities are filled.

e. See whether S. mutansis common in the mouths of Australian and Asian children
