Question 33:

Explanation: The exposure-outcome relationships in an observational study design that is used to assess outcome in cross sectional, case control and cohort studies which have the ability to control for multiple confounders. Therefore, in exposure-outcome studies, it is essential to have a control over confounding variables.

Therefore, the correct option is:

C.Conduct multivarite statistics to control for confounding variables.
